続いて、やってみる。

%dig iij.co.jp

[plan] plan 'iij.co.jp.' type 'A'
kr_zonecut_find_cached iijcojp
kr_zonecut_find_cached cojp
kr_zonecut_find_cached jp
[resl]   ns_fetch_cut ret 0
[resl]   NT check; iijcojp cut jp
[resl]   peek iijcojp ret -2
[resl]   peek cojp ret 0
[resl]   zone_cut_check -> ns_fetch_cut = 0

こんどはco.jpにゾーンがないことを利用して、qname miniは飛ばしている。

[resl]   
=> querying: '203.119.40.1' score: 11 zone cut: 'jp.' m12n: 'iiJ.co.Jp.' type: 'A'
[iter]   Update zone cut jp
[iter]   zonecut_add iijcojp NS dns0iijadjp
[iter]   Update zone cut iijcojp
[iter]   zonecut_add iijcojp NS dns1iijadjp
[iter]   <= referral response, follow
[ rc ]   stash referral NS
[ rc ]   stash auth for iijcojp
[ rc ]   stash auth for iijcojp
[ pc ]   => pktcache_stash entry
[resl]   <= server: '203.119.40.1' rtt: 6 ms

委譲・委任が返ってきたので、あとは同様だろう。

[plan]   plan 'dns1.iij.ad.jp.' type 'A'
kr_zonecut_find_cached dns1iijadjp
kr_zonecut_find_cached iijadjp
kr_zonecut_find_cached adjp
kr_zonecut_find_cached jp
[resl]     ns_fetch_cut ret 0
[resl]     NT check; dns1iijadjp cut jp
[resl]     peek iijadjp ret -2
[resl]     peek adjp ret -2
[resl]     zone_cut_check -> ns_fetch_cut = 0

ad.jpを確かめなければならないので、

[resl]     
=> querying: '203.119.40.1' score: 11 zone cut: 'jp.' m12n: 'ad.jp.' type: 'NS'
