我在碼頭集裝箱內。當我運行時：perl -Ilocal/lib/perl5 -MNet::DNS::Resolver -e 'print Net::DNS::Resolver->new()->query( "999781edb101" )'它什么也不回傳。
但是nslookup：
# nslookup 999781edb101
Server: 127.0.0.11
Address: 127.0.0.11#53
Non-authoritative answer:
Name: 999781edb101
Address: 172.16.16.7
為什么Net::DNS::Resolver不將主機名決議為 IP？
我應該配置什么才能使其作業？
謝謝
UPD
如果我使用debug專案，我可以看到它search xxx.com從以下位置查詢域/etc/resolv.conf：
# perl -Ilocal/lib/perl5 -MNet::DNS::Resolver -e '$r = Net::DNS::Resolver->new(); $r->debug(1); print $r->query( "999781edb101" )'
;; query( 999781edb101.xxx.com )

uj5u.com熱心網友回復：
從檔案和您的除錯輸出來看，您希望Net::DNS::Resolver->new(defnames => 0)將不合格的名稱（不帶點）直接傳遞給服務器，而不是始終附加默認域。
