> It works because it is actually the long form ("dotless") of

> 100, 1000, etc. In this system, it's 1, 256, 256^2, 256^3. So, an IP
> address of a.b.c.d works out to be:
>
> (a * (256^3)) + (b * (256^2)) + (c * 256) + (d*1)

> It's rather clever, actually. A neat geek parlor trick.

> It was also a recent security concern when someone discovered that the
> absence of dots caused Internet Explorer to misinterpret such
> addresses as
> intranet addresses, which then opened the browser to other
> exploits. Cool,
> eh? :/
