Re: [OT] Who can explain this address scheme?

[Bill_Royds]

Actually it is the reverse. The number you see is the real IP address. What we
commponly see (say 209.61.186.241) is a method of making it easier to remember
and parse.
IP addresses are just 32 bit numbers. But to make it easier to remember, John
Postel and the other developers of TCP/IP connocted a scheme to take the 32 bit
number, break it into 4 8 bit bytes and record the value of those bytes as
numbers between 0-255 separated by dots.
 so if you evaluate 209.61.186.241 as a 32 bit number we get 241
+256*(186+256*(61+256*209)) = 3510483697

Hi All,

I know this is off topic, but you all seem to be experts in IP and routing
in general.
I've received a few e-mails with http links pointing to some unusual
addresses.  It works, but the address is not a standard xxx.xxx.xxx.xxx,
rather a single string of numbers.
For example, I received an e-mail with a link to this address:
http://3510483697/
It's a website for a hosting service.  But HOW is that possible?  How are
those numbers translated to cobentional addressing schemes, or do they have
to be?
I'm just REALLY curious, and it bugs me that I don't know.

Thanks again in advance!
