This is the same IP address: 3232271615. You get that by interpreting the 4 bytes of the IP address as a big-endian unsigned 32-bit integer, and print that. This leads to a classic parlor trick: if you try to visit http://3232271615 , Chrome will load

Okay, but thats sort-of sensible, right? An IPv4 address is 4 bytes, so printing it as a single number is a bit human-unfriendly, but broadly plausible, right?
