>I think that did it, but let me clarify for myself... An IP address of 4 parts = 8 bytes consecutively in its binary 0/1 representation... Thats how the 222 sample you stated was a Class C network because 222 as the first segment of the IP is 11011110... regardless of the next 3 IP segments... Is that right?
Exactly. You can tell whether an address is of class A, B, C, D or E, just by looking at the first octet (byte). The binary representation is especially easy to remember.
If it starts with...
0 - Class A
10 - Class B
110 - Class C
1110 - Class D
1111 - Class E
