This is called a dword representation. A quick way to convert these
values is to use ping:
# ping 1078106110
PING 1078106110 (64.66.151.254): 56 data bytes
64 bytes from 64.66.151.254: icmp_seq=0 ttl=240 time=179.3 ms
64 bytes from 64.66.151.254: icmp_seq=1 ttl=240 time=146.0 ms
Some spammers will add 2^32 to the dword to make it even more obscure
but this only works with Internet Explorer. (Hey it's a _feature_ :-)
The follwing explains briefly how and why this works.
