-- ToshinoriMaeno 2011-07-11 00:34:45

$ dnsq ns nicoani.net ns1.ebuta.net

2 nicoani.net:
94 bytes, 1+2+0+1 records, response, authoritative, noerror
query: 2 nicoani.net

answer: nicoani.net 60 NS ns2.ebuta.net
additional: ns2.ebuta.net 600 A 163.43.164.227

これなら、ひとまず動く。 と思ったら、名前が違う。

5. これでは動かん

6. だが、サイトは見える

$ dnsq a nicoani.net a.gtld-servers.net

45 bytes, 1+1+0+0 records, response, authoritative, noerror
query: 1 nicoani.net
answer: nicoani.net 60 A 49.212.16.206

authority section, additional section なしの返事をするのが幸いしているらしい。 -- ToshinoriMaeno 2011-07-11 01:03:38
