kresd/example/3について、ここに記述してください。

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]

[iter]   Update zone cut jp
[iter]   zonecut_add iijcojp NS dns0iijadjp

}}}

委譲・委任が返ってきたので、あとは同様だろう。

{{{

[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、
