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 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.
