Tor 通过询问计算机的主机名来猜测它的IP地址，然后解析那个主机名。通常 /etc/hosts 文件里有指向旧 IP 地址的旧条目。

If that doesn't fix it, you should use the "Address" config option to specify the IP address you want it to pick. If your computer is behind a NAT and it only has an internal IP address, see the following Support entry on dynamic IP addresses.

并且，如果你有许多地址，可设置“OutboundBindAddress”，这样外部连接将使用你想要开放的 IP 地址。
