Good starting point for learning about IPv6?
Hey folks, Where's a good place to learn about IPv6? I've *mostly* got my head around IPv4 these days, and my ISP still only has an unsupported 6rd gateway which I've tried with momentary success on my router. I understand that the address space is 128 bits vs 32, that successive colons mean 0000 between them, that devices can have "local" and "global" scoped addresses, and it's *supposed* to do away with NAT... but that's about as far as I've gotten :) A server I lease overseas has an IPv6 address block assigned to it, and I'm struggling to figure out how I'm supposed to assign a reverse DNS to it, so Google and friends don't flag it for the MTA not having a reverse lookup (for now, I just lock it to IPv4)... I figured I might as well learn more about how it works, different to IPv4.. Any practical pointers?
I recommend following along with the certification here: https://ipv6.he.net/certification/ It's a reasonable intro Cheers, Brett On Wed, 25 Jul. 2018, 5:09 pm Anthony via luv-main, <luv-main@luv.asn.au> wrote:

That would be a good topic for a Saturday session. I could run it. On 25 July 2018 5:09:31 pm AEST, Anthony via luv-main <luv-main@luv.asn.au> wrote:

Sounds good to me. I mean we keep getting told that IPv4 is going to go away so I figure it's something worthwhile knowing.. Others'd be interested? On Wed, Jul 25, 2018 at 7:45 PM Russell Coker <russell@coker.com.au> wrote:

I would recommend reading RFC 8200 "Internet Protocol, Version 6 (IPv6) Specification", available from https://tools.ietf.org/html/rfc8200. I learned IPv4 (or more especially UDP & TCP) from RFCs 791, 768 & 793. Cheers ... Duncan.
