6rd ready?
せっかくの「World IPv6 Day」祭りですので、さくらの6rd（トライアル）で4ステップでWebサーバをIPv6に対応させる方法を試してみた。
さくらのVPSでサポートされるubuntu 10.04は残念ながら6rdに対応していないそうなのだが、kernel updateを含め6rdによるIPv6接続(Ubuntu10.04編)を参考にごにょごにょして
yano@vps:~$ ping6 www.kame.netてな具合になったので取り敢えず6rdの設定はOKっぽい。

続いてDNS方面で /etc/nsd3/bravotouring.com.zoneを
$TTL 3600てな感じに記述し、
@ IN SOA ns1.bravotouring.com. postmaster.bravotouring.com. (

yano@vps:~$ sudo nsdc rebuildてな具合になったので良さげ。
yano@vps:~$ sudo nsdc reload
yano@vps:~$ dig ipv6.bravotouring.com AAAA
