For those who want to try it at home:

ping 33333333
ping 55555555

I am sorry, two random Internet users in Korea and Germany, your IP addresses are simply special.

        IPv4 has some other features too.

        $ ping 0x8.02004010
        PING 0x8.02004010 (8.8.8.8) 56(84) bytes of data.
        64 bytes from 8.8.8.8: icmp_seq=1 ttl=116 time=22.8 ms
        

        That’ll be Google’s root DNS server, using hexadecimal and octal representations.
