Looks like octal and hex also work for that:

$ ping 01002004010
PING 01002004010 (8.8.8.8) 56(84) bytes of data.

$ ping 0x8080808
PING 0x8080808 (8.8.8.8) 56(84) bytes of data.

I wonder what would happen if a new top-level domain was created in a 
form that looks like a hex number, say "0x0". And then if someone 
registered 0x0.0x0.0x0.0x0. If ping sees that pattern, it interprets it 
as an IP. Clearly we need some out-of-band way to denote whether a 
string is meant to be interpreted as an IP or as a name, to avoid this 
problem in the hypothetical future where "0x0" is allowed to be a top-
level domain.  :)
