我的路由表出现了一些相当奇怪的问题。我运行的是 Debian Wheezy 系统，一段时间以来，每当我连接到家庭无线网络和 VPN 服务器（但不通过以太网）时，dhcp 都不起作用，并且计算机会获取链接本地地址：
$ sudo route -n
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 10.89.0.5 0.0.0.0 UG 0 0 0 tun0
10.89.0.1 10.89.0.5 255.255.255.255 UGH 0 0 0 tun0
10.89.0.5 0.0.0.0 255.255.255.255 UH 0 0 0 tun0
xx.xx.xx.xx 192.168.153.1 255.255.255.255 UGH 0 0 0 wlan0
169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 tun0
192.168.251.0 0.0.0.0 255.255.255.0 U 0 0 0 wlan0
但是当我跑步时route我得到了这个：
$ sudo route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default 10.89.0.5 0.0.0.0 UG 0 0 0 tun0
10.89.0.1 10.89.89.5 255.255.255.255 UGH 0 0 0 tun0
10.89.0.5 * 255.255.255.255 UH 0 0 0 tun0
authsrvr.com 192.168.153.1 255.255.255.255 UGH 0 0 0 wlan0

192.168.153.0 * 255.255.255.0 U 0 0 0 wlan0
域名“authsrvr.com”似乎不存在。dig对该名称运行查询显示该名称与网络上的任何主机均无关联。运行 whois 查询表明该域名为已暂停域名：

那么为什么我的计算机认为我的 VPN 服务器的域名是“authsrvr.com”？有人知道吗？
