Well, what the numbers mean vary upon what class IP address it is (Class A, B, or C. I think there are also classes D and E, but I honestly don't know much, if anything about them.)Originally posted by top
How do you read these?
Does the first numben indicate country/ISP or something, second stands for X etc. Is there some kind of a logic behind.
Class A addresses look like this:
with the N standing for Network, and the H standing for Host.
You can identify what class the IP address is by looking at the first octet (an octet is just a technical way of saying each section seperated by a dot). IP addresses whose first octet ranges anywhere from 0 to 127 is a class A address, IP addresses whose first octet ranges from 128 to 191 is a class B address, and any address that ranges from 192 to 233 are class c.
IP's aren't very easy to understand, at least in detail. The only reason I know anything on them (and there's a helluva lot I don't know about them still) is because I'm taking a cisco networking class at school, and a lot of the stuff we did in the first semester involved IP's (subnetting, DNS, ARP, crap like that).
But this page might help you out some in more information about IP's:
