Well, you have part of the "why" from the other answers. I'll give you the other half.
Back when the internet was smaller, and people were less concerned about the future, no one really expected the internet to get as big as it is today. This means that a whole lot of IP addressing space was wasted on trivial matters that did not come close to needing the kind of allocation that it was offered. The 127.0.0.0/8 network is a good example of this. Everything you send with a destination in the 127.0.0.0>127.255.255.255 range is looped back to your computer. All you really need for this is a single address. While some would argue that two or more loopback addresses would be practical, there is certainly no need for the 16.5 million addresses within the 127.0.0.0/8 network to all be loopback addresses.
That's really what it is. Short-sightedness. Ideally, the loopback address would be a class E address, not interfering with anything in the publicly routable address space, leaving 127.0.0.0/8 to be assigned as normal. The internet has never been a place of ideals, though. :)

This ip address range has been reserved for the loopback. Another way of thinking about it is the home address. The loopback is a way of giving the operating system a virtual network adapter.
If you typed 127.0.0.1 then you would be referring to your own computer.

No. 127.x.x.x is reserved as a virtual private IP class, mainly because of the range's origin of 127.0.0.1 as a loopback adapter.

This address block will not be allocated or assigned to any organization or ISP. Any packet with an address of this address block '127.0.0.0/8' cannot appear outside of a host system.

your network address is chosen by you, or you opted for default. If your having trouble accessing somthing on your network, get netscan (a free tool) that will scan your network and give you the ip as well as let you access routers etc.
