[ale] Running IPv6 on home server

[Chris Woodfield]

So, being a network engineer who's been hearing more and more  
rumblings about "we really should think about IPv6" at the office, I  
decided to figure out how difficult it would be to set up my home  
network as IPv6-enabled.

Truth was, it was a lot easier than I thought. :) I have a firewall  
and a server running Debian Etch, and a handful of Macs running  
10.4.x. Both OSes support IPv6 out of the box. I was able to get a  
free IPv6 /64 network allocation from Hurricane Electric's  
tunnelbroker.net site, followed their instructions to set up the 6- 
in-4 tunnel on the firewall, and enable radvd on the firewall to  
autoconfigure the hosts. For bonus points, I even enabled v6 DNS  
queries, added AAAA and ip6.arpa records to my zone, and configured  
resolv.conf on the linux server to use the v6 address of the  
nameserver for DNS queries:

admin at placebo:~$ host www.semihuman.com
www.semihuman.com is an alias for tino.semihuman.com.
tino.semihuman.com has address 216.27.162.41
tino.semihuman.com has IPv6 address 2001:470:1f07:44::41
admin at placebo:~$

I've confirmed that coming from a host inside my network, clients that  
are IPv6 enabled (Safari, ssh, etc) will use the v6 address to access  
tino. Can someone with a v6 address attempt to access http:// 
[2001:470:1f07:44::41]/gallery and confirm that IPv6 queries get  
properly forwarded?

Next question: While trying to get apps that are v6-enabled to speak  
v6 instead of v4, I noticed that DNS queries from the clients are  
still v4. Since my clients all get their addresses from a DHCP server,  
does anyone know if it's possible to configure DHCP to serve v6 domain- 
name-servers options? When I put in a v6 address in that field I got a  
config syntax error. Or is there a different way to "tell" v6-enabled  
clients about v6 DNS resolvers?

I'd be glad to share my experience for others who want to try this as  
well! Have any ALE meetings discussed IPv6 at all?

Thanks,
