整天的 ping 啊： -[ ping Network ] 最近网络是经常断，于是有整天的 ping 啊： crq@ $ ping 200.200.0.170 PING 200.200.0.170 (200.200.0.170) 56(84) bytes of data. 64 bytes from 200.200.0.170: icmp_seq=1 ttl=64 time=0.052 ms 某次突发奇想，猜她可能是 atoi 实现的数字转换，于是用上十六进制： crq@ $ ping 0xc8.0xc8.0.0xaa PING 0xc8.0xc8.0.0xaa (200.200.0.170) 56(84) bytes of data. 64 bytes from 200.200.0.170: icmp_seq=1 ttl=64 time=0.061 ms 换上八进制数： crq@ $ ping 0310.0310.0.0252 PING 0310.0310.0.0252 (200.200.0.170) 56(84) bytes of data. 64 bytes from 200.200.0.170: icmp_seq=1 ttl=64 time=0.062 ms 原来皆有可行也， 又某日，写命令时少了一个 0 ： crq@ $ ping 200.200.170 PING 200.200.170 (200.200.0.170) 56(84) bytes of data. 64 bytes from 200.200.0.170: icmp_seq=1 ttl=64 time=0.063 ms 原来亦是可行，于是干脆写成一个数了： crq@ $ ping 0xc8c800aa PING 0xc8c800aa (200.200.0.170) 56(84) bytes of data. 64 bytes from 200.200.0.170: icmp_seq=1 ttl=64 time=0.064 ms 最原始的，换为一个十进制整数： crq@ $ ping 3368550570 PING 3368550570 (200.200.0.170) 56(84) bytes of data. 64 bytes from 200.200.0.170: icmp_seq=1 ttl=64 time=0.078 ms 全都可行，不知这种点分十进制的写法是否在某篇 RFC 已冥冥中早有注定？ 后来再以M$的 ping 测试一下，也是同样： D:>ping 3368550570
