我有一个奇怪的问题绑定所有我想要的是能够通过特定的DNSparsing一台主机
在named.conf我添加：
zone "myhost.example.com" IN { type forward; forwarders { 10.10.10.11; }; }; caching重新加载+刷新后
当我运行挖掘我只有一个CNAME：
; <<>> DiG 9.9.4-RedHat-9.9.4-38.el7_3.3 <<>> myhost.example.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 29985 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 ;; QUESTION SECTION: ; myhost.example.com.

奇怪如果我在TCP挖掘过程中，我看到Alogging被回答我的绑定服务器：
:29:18.762280 IP (tos 0x0, ttl 64, id 51042, offset 0, flags [none], proto UDP (17), length 78) XXXX9274 > 10.10.10.11.53: [bad udp cksum 0x4218 -> 0x1b5c!] 12136+% [1au] A? myhost.example.com. ar: .

我有点想法，我做错了什么？ 在此先感谢问候
