Introductory post: this is my public sub-account for #IPv6 content; my main account is linked in my profile.
I support the complete roll-out of IPv6, including intermediate efforts like dual-stack support and #NAT64 #DNS64 #CLAT, with the ultimate goal of native IPv6 support in all-new deployments, using RFC standards and best practices.
I support subnets no smaller than /64 (#SLAAC), ISPs should delegate prefixes of at least /56 or /48, and #ICMPv6 should be rate-limited, never blocked.
