情况如下：
- 我可以 ping 并连接到 localhost / 127.0.0.1
- 我可以解决
hostname(dig/nslookup) - 我可以从另一台机器 ping 我的本地 ip 地址（10.63.66.185）和主机名
- 我可以从另一台机器连接到本地机器上正在运行的服务（nc -l 12345）
- 我无法 ping/连接到我的本地 IP 地址 (10.63.66.185 -> 10.63.66.185)
- OSX 防火墙已关闭，且未运行其他安全产品
- 路由表看起来不错（lo0 存在且 10.63.66.185 -> lo0）
- 即使重启后它仍然存在
所以我很困惑为什么我无法连接到自己的 IP。有人知道或需要更多信息吗？这是路由表：
