ipv6 - baby steps

everybody talks about IPv6 and still too few of us take it seriously. on polish mailing list dedicated to implementing IPv6 we get steady series of IPv6 prefix announcements, but real services available over this protocol is low.

as a proof of concept for upcoming PLNOG, i just launched full network stack (Cisco 7200VXR with NPE-G1, ASA 5500-X, Catalyst 3750) and service (FreeBSD) for dual stack operation. IPv6 should be preferred, and while there’s still some things to tune down (like for example, DNS resolver in Windows XP), it should work.

so… it can be done, and in the worst case even over tunnel brokers, so you don’t need to ask your SP for IPv6 prefix delegation.
