IPv4 just got a whole lot more interesting. I had no idea you could do that.

(Note: the above address points to Google. If it's not working for you, sorry; I've only tested with Opera)

http://011237241544/ <- octal
http://0x4a.0175.67.0x64/ <- hex.oct.dec.hex

Weird.

Octal works for me, but hex doesn't -- I'm guessing it's because Opera uses some sort of alternative syntax for hexadecimal.
It gave me the idea of making a tinyURL clone that produced URLs like http://1249723236/797291/. Of course, I'd have to learn how to write such a site, first, and get a site with a dedicated IP, which doesn't usually come cheap.

But... how does it differentiate between the groupings if they don't all have three digits? Do you put in zeroes or something?

1249723236 (decimal) - Convert entire number to hex ->
4A7D4364 - Divide into four groupings ->
4A.7D.43.64 - Convert each group to decimal ->
74.125.67.100

Yeah, what LV said. They aren't each converted individually, they're combined the same way 2 and 5 are combined in the number 25 (except it's all converted to hex during that process).

...Also, I believe OpenDNS uses this technique to mask URL hosts. Interesting indeed.

This would make an awesome feature on therealn (Like Scythe said with doing it like tinyurl).
