在我的 Ubuntu 12.4 上，这些工作正常：

$ hostname
my-machine-XX

ping `hostname`
ping my-machine-xx (192.168.0.69) icmp_req=1 ttk=64 time=0.043 ms

但 host 和 nslookup 返回错误的 IP 地址：

$ host my-machine-xx
my-machine-xx has address 198.105.244.23
my-machine-xx has address 198.105.254.23
Host my-machine-xx not found: 3(NXDOMAIN)


$ nslookup my-machine-xx
Server:     127.0.0.1
Address:    127.0.0.1#53

Non-authoritative answer:
Name:   my-machine-xx
Address: 198.105.244.23
Name:   my-machine-xx
Address: 198.105.254.23

我很感激有关如何修复它的帮助。谢谢。
