I need IP Addressing explained in brief
When looking at an IP address, I would like to be more familiar with how to determine some BASIC criteria about that address.
I know there are some things you can tell from just the number alone and so I first want to know only the basics.
For Instance:
Is the number Internal or External
What are the various ranges and what are the generalities I need to be aware of?
It's hard/fast rules I am after.

<<Could you expand on the meaning of the word "range" a little further?
The range is simply all the valid IP addresses in the particular network. Range just means from 192.168.0.0 to 192.168.255.255.
So it would include all network IP addresses
192.168.0.1
192.168.0.2
192.168.0.3
192.168.0.4
192.168.0.5

>"It is generally considered, though not always the case given the range we talked about that if the IP starts with either 10, 172, 192, or 169, it's an internal IP"
Yeah, i would agree with that. To be more technical, the 10, 172, 192, or 169 would be called the first octet of the ip address.

Yeah, i would agree with that. To be more technical, the 10, 172, 192, or 169 would be called the first octet of the ip address.
Example...192.168.0.2
192 = first octet
168 = second octet
0 = third octet
2 = fourth 0ctet
192 = first octet
168 = second octet
0 = third octet
2 = fourth 0ctet

ANOTHER QUESTION:
I just made three pages in One Note based on your response. That is EXACTLY what I wanted and I will expand my knowledge. For expansion sake, when you say "range", I'm not clear how to make sense of that in my pea size (desktop support tech) brain. Could you expand on the meaning of the word "range" a little further?
ANOTHER QUESTION:
To consolidate even further, would this be an accurate statement:
"It is generally considered, though not always the case given the range we talked about that if the IP starts with either 10, 172, 192, or 169, it's an internal IP"
