I know they are made up of 4 octets, example:
111.222.23.123
Okay, now I want to know what each Octet means.
I have about 10 sites hosted on one host - each with its own virtual server with different IP addresses.
The first octet never changes - 64. What is this? The country it is in is my first guess?
The second octet changes over my 10 sites but not much. The last two octets seem random.
Can somebody please explain how the servers are assigned their IP addresses and what each Octet means?
Nerdy question I know, but it's been bugging me, I can't find the answer, but I guess it's real easy.

Every computer in the world which is connected directly to the net (without proxy/nat servers) will have its own unique IP address.
An IP address is like a finger print in a sense, only one computer in the world could be using the IP at the same time on the internet.
The numbers mean nothing more than a way to ID the computer. Some blocks of IPs, such as 210.210. might be delegated to China for their IP space, 210.211. might be deleted to japan for their name space but there is no Definitive way to tell which country the IP belongs to, although some geotargettingn scripts come close.
