Debian got a /48 of IPv6 addresses yesterday and I used them to create a couple tunnels and bring more of our machines onto the 6bone. For those that are not familliar with IPv6.. a /48 is large enough to hold about 64000 subnets if you use the usual configuration scheme. Each of those subnets can contain the largest switched ethernet network you can build (> 10000 hosts).

Debian Potato will have quasi usful IPv6 support in many packages, woody should be even better. The problem is getting upstream to accept patches. I wish more people writing socket/network applications would look at RFC2553 and visit the Man Page viewer at OpenBSD.org and look up getaddrinfo - that will enable their App for IPv6 pretty much right off. glibc since 2.1 has supported the functions, but there are no man pages since it is GNU.
