6rd ready?

IT

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
PING www.kame.net(2001:200:dff:fff1:216:3eff:feb1:44d7) 56 data bytes

rtt min/avg/max/mdev = 18.899/19.030/19.113/0.184 ms

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
@ IN SOA ns1.bravotouring.com. postmaster.bravotouring.com. (
                201106031730 ; serial
                10800 ; refresh
                10800 ; retry
                604800 ; expire
                86400 ; default_ttl
        )
@          IN   NS     ns1.bravotouring.com.
           IN   NS     ns2.bravotouring.com.
           IN   A      49.212.38.155
           IN   AAAA   2001:e41:31d4:269b::1
           IN   MX 10  mail.bravotouring.com.
#@         IN   TXT    "v=spf1 a:mail.bravotouring.com ip4:218.219.101.229 ~all"
@          IN   TXT    "v=spf1 a mx ip4:49.212.38.155 ~all"
#mail.bravotouring.com. IN   TXT    "v=spf1 a ip4:49.212.38.155 ip4:218.219.101.229 -all"
ns1        IN   A      49.212.38.155
mail       IN   A      49.212.38.155
www        IN   A      49.212.38.155
ipv6        IN   AAAA   2001:e41:31d4:269b::1
vps        IN   A      49.212.38.155
ns2        IN   A      49.212.38.155

てな感じに記述し、

yano@vps:~$ sudo nsdc rebuild
yano@vps:~$ sudo nsdc reload
yano@vps:~$ dig ipv6.bravotouring.com AAAA
; <<>> DiG 9.7.0-P1 <<>> ipv6.bravotouring.com AAAA
;; global options: +cmd
;; Got answer:

てな具合になったので良さげ。

apache方面は何もしなくても

yano@vps:~$ telnet ipv6.bravotouring.com 80

な具合だったので、これでIPv6は万事OKですかね？
