ITidiots 72: IPv6 Essentials
Monday, December 21, 2009 at 10:11PM Well I am sure you have heard that we are running out of IPv4 addresses. Now I, like no doubt some of you, have been hearing this for around 15 years, in fact ever since I learnt TCP/IP I knew it was doomed. In this episode we introduce IPv6 concepts and cover the basics of the new IPv6 address format. Oh, and sorry for the sound quality on this one, the batteries in our microphone ran out, and Mark was suffering from man flu!

Could you provide PPT? :D
I found that interesting from an IPv4 point of view and it answered my question about IPv5... but what about IPv1,2,3 and what would the next big thing be?
Also, IPv6 was a little confusing in this video, any little pointers to either guides on the internet or youtube (or any other generic free video sharing site) videos?
Other than that, great to have you back guys!!
Edit: Next time, put SuFay on the camera as well...
forget Pv1,2,3 and 5 theres no point going down that road.
"what would the next big thing be?"
getting IPv6 out there first! .. getting everyone to agree to use it , including countries ... IPv6 isn't that new !!!
"(or any other generic free video sharing site) videos?"
best one I have seen is the one from the google conference that i posted here. (ill find it for you)
I would also point that MS have their MS'ified Pv6 standards, it may be slightly different on other platforms e.g. number of IPv6 addresses each client has for one. There's also tech such as DHCPv6 which still allows admins to statefully assign addresses if they wish instead of auto-configuration, in fact cisco backs this. In fact many IPv4 services have been updated for IPv6.
There are also problems that still need addressing, such as p2p and streaming style services which may have to use a more expensive client server models.

It is all well and good, more addresses, (I guess) more security and less work having to program in addresses as they work on their own... but what happens when (for example) I want to access a remote server (e.g. a private web hosting one) or say, my home router? I would have to type in a huge long address and try and remember it, is there anyway of "masking" an IPv6 address as an IPv4 one?
All devices will probably have a simple address as a factory defualt to configure eg ::1
Also IPv6 has LLMNR (link local multicast name resolution) which allows you to give devices friendly names its like a peer to peer version of DNS/host file.
So if your IPv6 router has LLMNR, you could login set its name as "router" and local all devices will atomatically be able to resolve its name "router".
Stuff on internet and large networks will still use DNS
"Pv6 address as an IPv4 one"
There a few ways to gateway IPv4 and IPv6 as yet there is no offical standard.
A special version of NAT is one option.
MS as has special addresses which are made from IPv4 and IPv6, however, i belive this is for support on local networks where programs use IPv4 via MS apis and dont use IPv6 yet
""""" its call embeding i belive
eg 222.1.41.90 = 0:0:0:0:0:FFFF:222.1.41.90
I belive the way MS have done it you'll have double stack and your IPv4 address will be made into yet another IPv6 IP like the one above. This is IPv4 over IPv6
Like i said ipv6 over ip4 you could use a gatway or use tunnel between sites or devices over ipv4 (this is how most brokers work effectively its a tunnel to a large sperate IPv6 network joining everyone together, this is the way it have to be on the net until everyone moves over to fill the voids)
nice, that last post of yours just helped a lot... thanks!
I guess IPv6 will take off now a bit like 64bit at home...
Any reason why this never hit iTunes?
It is just in the lower resolution podcast, subscribe to Itidiots (mp4/ipod)
Yep, for some reason, even though the other (SAN episode) was recorded using the same video equipment (that has HD and mp4 versions) the IPv6 one doesn't have a HD episode... (Dave?)
Still, it is still good quality for an mp4, ipod podcast
anyone know any other podcasts, i think itidiots has pretty much had it for the time being.
not any more video ones like this. There are of course the ones with big americans talking out the back of their a*ses for two hours with adverts every five minutes.
Best of YouTube, Gadget TV, HowCast, to name a few good ones...
if it was more of a community then there would be new content between episodes.
I would love to help, i have lots of ideas, but i get the impression that they don't want it.
Jamie, you are evidence that Americans don't have the corner on the market on talking out of their a*sses. Very rude! Grow up!
Yes it was rude of Jamie "the thread killer" ;-)
cough...sod off jam.. cough
lol, well I can't stand some of them... and I think I was in a bit of a mood that day (won't go into it, thought it was technical) and I did censor it (sort of)...
I would be more than happy to either:
a.) Go on Unwatchable (skype does work on my laptop, and now my PC)
b.) Create content for the site...
or
c.) leave itidiots.com ?
