为什么 Net::DNS::Resolver 不 return 本地主机的 IP？

Question

我在 docker 集装箱内。当我运行：perl -Ilocal/lib/perl5 -MNet::DNS::Resolver -e 'print Net::DNS::Resolver->new()->query( "999781edb101" )'它returns什么都没有。
但是 nslookup 会：

# nslookup 999781edb101
Server:     127.0.0.11
Address:    127.0.0.11#53

Non-authoritative answer:
Name:   999781edb101
Address: 172.16.16.7

为什么 Net::DNS::Resolver 没有将主机名解析为 IP？
我应该配置什么才能使其正常工作？
谢谢

UPD
如果我使用 debug 项目，我可以看到它从 search xxx.com、/etc/resolv.conf:

查询域

# perl -Ilocal/lib/perl5 -MNet::DNS::Resolver -e '$r = Net::DNS::Resolver->new(); $r->debug(1); print $r->query( "999781edb101" )'

;; query( 999781edb101.xxx.com )

;; udp send [127.0.0.11]:53

从文档和您的调试输出来看，您希望 Net::DNS::Resolver->new(defnames => 0) 将不合格的名称（不带点）直接传递给服务器，而不是始终附加默认域。
