New post: IPv6 Foundations.

IPv6 isn't "the future of the internet." It's the internet. IPv4 is the relic we keep alive on NAT life support.

A laid-back tour through the basics: how the addresses are built, the two rules for crushing out the zeros, a /64 per subnet so you stop counting hosts, SLAAC, and why blocking ICMPv6 is a self-inflicted wound.

And no, dual-stack isn't a destination. It's a burden.
