@Baruce:  Fred does good classes! Also, Embarcadero is running courses in CPP or Delphi to Generate Android Apps -- talking to external sensors etc is a possibility with either.

Check the Embarcadero Web Site.

Iron

@78RPM

@DaveWR

Thank you for directing me to the classes by Fred Eady.

I did not attend class yesterday, and I just now catching up with both the comments from last Tuesday, and yesterday's class presentation.

Tonight or  tomorrow I'll let you know whether or not I was able to view Mr. Eady's classes.

Again, thanks!

 

Iron

We have just finished a bunch of enhancements to support UP{v6.

Iron

Thanks for the lecture, Don.

Iron

If they had to work out every last detail before deployment, the deployment schedule would drag on and on. IPv4 was already just about out of addresses. What Don said about the RFCs, that's how they've (IETF) done it up to now.

Iron

@ Don ; yes, but my point is exactly that ; instead of "patching" something afterwards if it could just be thought out while working on it...   ;-)

Avoids breaking something !

Iron

Thanks Don & FireFlyBlu !

 

Iron

Thanks for the presentation

Iron

If things are "still (apparently) being sorted out.", when is the "full roll-out" of IPv6 planned ?   Shouldn't all this already be decided / published / known ?

 

It is already active in many areas. China is all IPV6

Iron

The "other job" is calling - I will see all of you tomorrow!  THANKS AGAIN for your participation!

Iron

@StephT - That's the beauty/pain of the Internet! Nothing is ever ratified! "Requests For Comment" (RFCs) are published, and if enought people start doing it, it becomes the standard.

Iron

@Charles - Off Topic - Is the content for the MQX that you planned to post to your web site now available? Can you post a link?

Iron

So Charles, is Freescale ahead of other IC manuf. regarding v6 availability ?

Iron

Releasing a new std w/o poking holes in it opens it up to the underground again. Although it is a tracked system. The rest you here on the news.

Iron

I am really looking forward to the Sept class on this! I am also developing a live hands-on class that will launch soon.

Iron

If things are "still (apparently) being sorted out.", when is the "full roll-out" of IPv6 planned ?   Shouldn't all this already be decided / published / known ?

Iron

In the ISP's case, will they still have to manage the internet DNSes, or they are to become redundant, too?

Iron

We are still in the formative years of v6. Much to be worked out for some of these issues!

Iron

Proper recycling would take care of some of the address release

Iron

Also the upper level domain will be going private (US is no longer going to control) they are still haggling over it, it's something to see

Iron

I would hope.  A lot of this is still (apparently) being sorted out.

Iron

@ Charles :  I think the capability to retire an IPv6 address will exist. Right now everyone is dealing with blocks. But the process is there, using dynamic addresses.  

 

But in addition, I would be concerned that thrown away devices with a fixed IPv6 adr is just waisting a "non-renewable" ressource !

I hope that adr could be reused ; say part of a WEEE process ?

Iron

Good question - I have not looked into the allocation for v6 addresses to see if there is any policing going on against 'squatting'

Iron

How will IPv6 assignments be similar to MAC address assignments? Some NMS packages actually identify the manufacturer of a given device - or at least the manufactuer of it's TCP/IP silicon - by its MAC address, since blocks of MAC addresses are assigned by manufacturer.

Iron

will there be IPV6 block squatting?, like domain squatting. Think ISP will allocate as long as you pay, else it will default (your block) back to the open addresses

Iron

@cghaba - I imagine things like autonomous drones that move around will have to have their own IPv6 address since they will not always be within the range of a specific private network.

Iron

I think there is some of both - there is still patching to IPv4 going on as well as full v6 implementation. But remember it has to talk to v6 routers to work.

Iron

@78RPM - I think the capability to retire an IPv6 address will exist. Right now everyone is dealing with blocks. But the process is there, using dynamic addresses.

Iron

Many claim that there is not appreciable additional computing, as legacy systems will go away so you are replacing code not adding. My feel is that there will be possible need for more. BUT not in all cases. A node within a subnet will need no more code or horsepower in IPv6 than in IPv4

 

This is true, it is just all about trying to  expand addressing on the exsisting network w/o rebuilding it

Iron

In the transition to IPv6, for the IoT world will we see IPv6 implemented in the IoT device or more probably in hubs to which IoT devices will be connected?

Iron

You really need to step back and understand the basics of what you are communicating through and the transistion 4 to 6. Without it all will be in vain. Study the transition than apply that knowledge to your projects. Might as well learn it now that fight with it later.

Iron

?? @Charles, not that we worry about running out of 128-bit addresses, but what if a device is tossed into the recycle bin -- is there a way of retiring its IPv6 address, too?

Gold

Many claim that there is not appreciable additional computing, as legacy systems will go away so you are replacing code not adding. My feel is that there will be possible need for more. BUT not in all cases. A node within a subnet will need no more code or horsepower in IPv6 than in IPv4

Iron

Thanks Charles and Jennifer for this interesting lecture. 'Til tomorrow!

Any references on data acquistion micros with an embedded IPv6 stack?

Iron

any experience with/recommendations for IPv6 support for Cortex M4?

Iron

Charles' question was: Are you seeing v6 support for your silicon / OS? Good/bad?

I've not seen IPv6 support yet.

Will the implementation of IPv6 need more processing power?

Iron

Multicast Listener Discovery - needed for joining and leaving multicast groups - is already to v2.

Iron

@cpu, others ignore. Yes, I'm considering new system. I'll try to check in with you just before class starts tomorrw so as not to use this "band width."

Gold

The links that @FireFlyBlu listed are exellent.  plus the links that I posted

Iron

Mr Lord what was your ref to (IPV6) v2 was that refering to a address to text representation or other

Iron

@Don Pancoe and Charles, thanks, I'll look that up.

Gold

Thanks Charles and Jennifer

Iron

@78RPM - yes. Actually the three classes of licensing went away a while ago when they started to run out of the blocks.

 

Iron

@78RPM - Classless Inter-Domain Routing already eliminated that even in IPv4.

Iron

@danlafleur - yes, edge of seat class! I'd hate for someone to nod off...

Iron

?? @Charles, Does IPv6 eliminate the Class A, Class B, and Class C licencing of IPv4?

Gold

IPv4: you call out to your lab-mate "the device is on .20".

IPv6: "The address is FE80 colon colon 03FF colon FE04 colon 0506..."

Iron

Thanks, Charles, Jennifier, and, course, DN and Digikey!

Iron

Thanks Charles, only needed the edge of my seat for this class. No time between slides to sit back. See all tomorrow.

Iron

lots of good information to go through.

Blogger

Going from IPv4 to IPv6 seems analogous to going from RS232 serial to USB. So much more complex. So much capacity for growth. But it was so easy and convenient when we could ping 192.168.0.20, and so on.

Iron

Really good slide deck. Thanks

Here is a little help if you wish to pre prepare:

The 128 bits of an IPv6 address are represented in 8 groups of 16 bits each. Each group is written as 4 hexadecimal digits and the groups are separated by colons (:). The address 2001:0db8:0000:0000:0000:ff00:0042:8329 is an example of this representation.

Iron

Thanks Charles and Jennifer.

Iron

Very good session, very informative Thank you very much

Thank you Charles & Jinnifer

Iron

Thanks Charles, very interesting lecture

Iron

Are you seeing v6 support for your silicon / OS? Good/bad?


not required yet, maybe in the future

Iron

Great lecture. I am still none too saavy on the IoT etc. security.

I shall study up now and tomorrow...

It would be helpful to get the power point slide show earlier

so I could have studied more alphabet soup when I have weekend study time sir.

Iron

a drink from a firehose !!

Iron

Ne habla Decaf @FireFlyBlu

Iron

No I haven't seen support for IPv6 yet, in tha chips Im dealing with.

Thanks Jennifer, Charles, and Digi Key. Great lecture.

Iron

Thanks Charles and Jennifer.  See you tomorrow.

Iron

Thanks Charles, Jennifer, Steph, and DigiKey

Iron

Thanks Charles and Jennifer.

Gold

Thanks Charles and Jennifer.

Iron

Thank you Charles.

This subject is way beyond what I will ever use, but at least I know what exists.

 

 

Phew, thanks Charles!

Feel a little overwhelmed with IPv6.

A lot to learn I guess!

Iron

Thank you, Charles, Design News, and Digi-Key.

Gold

@jmelotte

Visit this page after this is over some other time. All will preserved (for a while.)

 

Iron

Thanks for the introduction, it is good to have as we are starting implementation.

Iron

A sample design work through would be nice.

still mixed experience with IPv6 for Cortex M4...

Iron

@78RPM I responded to your 24-bit audio question. Look early in the chat.

Iron

Thanks - The IPV6 overview had a lot of stuff I didn't know

Network Addressing is not within my core functions; I'm not involved with Network Architectures of any scope.  But this overview of the depletion of 32 bit IPv4 and the expansive nature of IPv6 was eye-opening, thanks.  Glad there are those of you involved to keep my links up and running! Thank you!

Thank you Charles and Jennifer.

Iron

To future proof IPV6 needs to be integrated

Iron

Very interesting.  Thank you.

Iron

I've not looked as silicon-provided IPv6 offerings (no need) ; I'll have to pay attention.  Any comments on who has some available ?

Iron

That was a whirlwind of info. Definitely look forward to an IPv6-specific class.

Iron

We have not seen support as of yet, but it is early in our program.

Iron

Thank you Charles and Jennifer.

Iron

Thank you for this 'tiny touch stone' of IPv6.  One of the clearest I've seen.

Iron

Not implementing yet

 

Iron

A doubt, for EUI-64 RFC say that sttufing was in MSB or bit 7; that is the first bit starting from left, why in all figures that I consult suff bit 1?

Iron

IPv6 is not yet a priority in the chips I see.

Iron

Thanks Charles.  Very informative!

Iron

Wow!  A lot of material in a short time. Outstanding.  I will be back for September 8 IPv6 class.

Thank you Charles and Jennifer.

Iron

I prefer to offload the whole issue to someone else. I work on other parts of the design.

Iron

Yes, QNX, the RTOS we use, has supported ipv6 for several generations of their network-stack

Iron

Are you seeing v6 support for your silicon / OS? Good/bad?


Not looking into it yet.

Iron

Not required yet.

Iron

We are just beginning to explore the possibilities of IPv6.  Security is huge concern

Iron

Not yet working in IPv6

Iron

@jmelotte, you simply must scroll through the resposnes, and if your question was not answered, ask the question again.

Iron

I'm not working with IPv6 so I haven't had need for support yet.

Iron

Not really working on IPv6 yet, so can't comment on support.

Iron

Have not sought support for IPv6.

Gold

Not yet working in IPV6.

Iron

pretty good library support

Iron

Not implementing IPv6 yet.  Stay tuned.

Iron

Not working at silicon level.  Working at device level.

Iron

Charles' question was: Are you seeing v6 support for your silicon / OS? Good/bad?

dear,

up to know i could really follow the chat on line. the mesage follow far too rapidly.

what can be doen; and are they saved somehow?

also no way to check answers on my quaestions.

Iron

You should be able to verify a ipv6 device through a site look up, like FCC devices right?

 

Iron

@cjlord - IP V6 testig and certification  -  do you kknow a cost range for this service?

Iron

That's cool...  can verify IPv6 compliance

Iron

Do you see a need for Secure ND?

slides day 3; up to now i didn't see mentionning references on this material; will this be done ?

Iron

What types of security are you seeing a need for?


vpn and ssh

Iron

Slide 27 answers my question about whether or not MAC addresses change

Iron

Securing internet transmission for access codes

Iron

Security would be needed for User control for data types access, functional access

Iron

TLS, certificates instead of passwords

Iron

Charles' question was: What types of security are you seeing a need for?

TLS, SSH and PVN

Security for customer data.

Iron

Charles' question was: How is this different from IPv.4?

IPv6 doesn't need DHCP, NAT. Multiple LP addresses per interface.

At what level the subnet gets defined? Is this the regular network admin, like the one who interfaces with the ISPs?

 

Iron

i said before:

is there out there some a pdf or .. on the netwerk-elements and )subelements in thesed ay 3 slides ?

 or is this not necessaty ?

where is the limite of background knowledge on this ?

Iron

Security is an essential consideration but it is balanced with power requirements.

Iron

Q: What types of security are you seeing a need for?

A: Adequate security for the application.

Iron

Data and Access Security

Iron

IPSec is the security system I'm most familiar with since I largely work on "air gap" networks, meaning they are not connected throught the outside world, or are only connected through a very few, heavily firewalled and IDS-protected points.

Iron

Working on interfaces that send data over cellular networks. Need access to devices to be secure.

Iron

privacy for personal information.

network protection.

Iron

Security now - semi-custom encrypt/decrypt mixed with public domain solutions.

Iron

What types of security are you seeing a need for?


Keeping the customers data secret.

Iron

I let others determine security issues

Iron

software feature unlock codes need security and a concern here for new products.

Iron

Security in home security and surveillance

Iron

Mil has it's own netwrks

Iron

Mostly considering security of chips themselves and immunity from hacking and theft of Intellectual Property (IP)

Gold

still using IPv4....but our customers are slowing moving to IPv6

Iron

Usually TLS, SSH, and VPN.

Iron

I have not used IPV6 yet

Iron

Charles' question was: What types of security are you seeing a need for?

rfc = request for comment(s)   an Internet Engineering Task Force memorandum on Internet standards and protocols

Iron

Working with v4 but will have to ultimately address needs of v6

Iron

ipv6 supports multilink subnets

Iron

I'm working in IPv6 now but mostly in IPv4

Iron

I meant to say I am familiar with v4. Is the difference that you have a "subnet" spanning a router in subnet 8a?

Iron

haven't done much with ipv4

Iron

Charles' question was: How many of you are already working in IPv.6?

Mostly our clients use LPv4

is there out there some a pdf or .. on the netwerk-elements and )subelements in thesed ay 3 slides ?

 

Iron

haven't dealt with IPv4 in detail.

Iron

http://en.wikipedia.org/wiki/Ipv6

Iron

I'm not familiar with v4 and I'm not seeing anything radically different. Maybe by the time we finish today's session.

Iron

Q: How is this different from IPv.4?

A: Not yet familiar with IPV4/IPV6

Iron

Host tables and/or DHCP seems to be missing.

Iron

How is this different from IPv.4?


not sure

Iron

I don't see DHCP. This raises a question about IPv6 I will ask later.

Gold

I'd liek to learn more about how this IPv6 topology is different from IPv4.

Iron

Different: not all addresses global

Iron

I don't know enough to say.

Iron

Didn't went into details

Iron

One difference is that subnet 8b has a router within it

 

Sorry, not familiar with this.

Gold

I haven't needed to deal with this level of detail

Iron

Charles' question was: How is this different from IPv.4?

where i can find more on the slides of day 3 ?

 

Iron

Your slides are incorrect, subnet in only in the fourth hextect and ocassionally extented to fifth.

 

Iron

wondering same thing as mechlab

not working with ipv6

Iron

planning a partial conversion to IPv6 in the next 6-12 months, as the iNet-connected gadgetry encroaches upon our IPv4 limit.  (internal network gadgets don't have this problem)

hello all from Timisoara

Iron

How do you handle security if everything now has an external routable address via ipv6?  Firewalls just preconfigured to only allow certain endpoints or some other sort of authenticated pass through?

 

Iron

Iron

@78RPM I don't think I have listened to 24-bit audio. Are you considering a new music playback system?

Iron

Looking into it for new project

Iron

The old PLC's don't use IPV6 and are incompatable

Iron

How many of you are already working in IPv.6?


Not working inv.6

Iron

We are working in IPv6 and enduring the learning curve.

Iron

Not working on IPv6 ; I'd leave that to the MAC IC maker for now (i.e. (semi) transparent for now)...

 

Iron

We've been making all our embedded code IPv6 compatible for the last 2 years...

Iron

ipv6 still not activated here

Iron

yes - already working in IPv6 and gotten through the full conformance from IPv6 Gold and USGv6

Not working with IPV6.

Iron

Charles' question was: How many of you are already working in IPv.6? Not currently working in IPv6 but am very interested in it

Iron

Still stuck at IPv4

Iron

I have not used ipv6 yet

Iron

Not yet working in IPv6

Checking into it.

Iron

Not working in IPv6 yet. I've finally gotten an intuitive understanding of IPv4 addressing and now I have to learn something different.

Iron

Not currently working with IPv.6

Iron

Have not needed IPv6 yet because I just use private networks.

Gold

no IPv6 for our embedded systems... yet.

Iron

Hello from sunny Ankeny, IA

Hi from Cambridge MA

Iron

@cjlord, I just finished looking over the slides and found them to be the best explanation of IPv6 I've seen yet.  I have a question that I did not see answered on the slides.

Say I have two IPv6 devices, Dev_A and Dev_B, and I want to transfer data from Dev_A to Dev_B.  They both have autoconfigured IPv6 addresses, but how does Dev_A know what Dev_B's address is?
