What kind of URL is this?

http://3564020356/

The above URL I stumbled upon from hackergames.net. It's the first time I've ever seen an URL like that one.

Can anyone tell me how come that URL is just 3564020356?

Thanks

This is a usual address but the domain name is coverted like when you convert a domain name to the IP address.
I don't know how to convert an IP to such numbers but I'm sure somebody will answer you here.

Check this:

3564020356 is the same as 212.110.162.132 which is the same as mktweb.planet.it .

Gotta love SamSpade ( http://www.samspade.org/t/ ) :)

Anyway, about the encryption: I asked this same thing in the IRC a couple of months ago and someone instantly enlightened me (forgot who, credits to him anyway!).
It's like base 256 numbers:

212.110.162.132
First there are 132 times of 256^0 (=1)
then 162 times 256^1 (=256)
then 110 times 256^2 (=65.536)
then 212 times 256^3 (=16777216)
and when you sum up all those things it gives out the huge number of 3564020356

Voilá.

Thanx. A useful resource.

Ah, URL hyjinks again... Hmm. Just off the top of my head, you can also have cases such as:

http://[email protected]/
http://USERNAME:[email protected]/

And that sometimes you will get ones like:

http://www.cnn.com/SCI-TECH/news/Gat...4020356/gates/
http://www.cnn.com/SCI-TECH/news/Gat...4020356/gates/

in which case you are actually going to (borrowed the dword and translated ones from above)

http://212.110.162.132/gates/

with some user/pass info that your browser will ignore (the server probably never requests it.)


Tricky stuff. And none of those urls are meant to work. :)
