Mike Meyers (All-In-One) says that IP addresses are somtimes referred to as
dotted-octet notation and that an IP address cannot contain the number 255
as it is represented by all 1's. Is this not incorrect as I am a major in
computer networks and I thought IP addresses were referred to as
dotted-decimal notation. The word octet means to represent a number using
on 3 bits. Also, I am pretty sure 255 can be in your IP address as long as
it's not the last number otherwise it would be broadcast.

An IP address in decimal form is dotted-decimal

255.255.255.0

An IP address in binary form is dotted-octet

11111111.11111111.11111111.00000000

An octet is 8 bits

As far as the IP address goes I wonder in what context that statement was.
IP address is general refers to all IP addressing, including reserved
addresses and is only limited by the 8 bits, hence 255. The last octet in a
Host IP or a Network address can never equal 255, and they will never begin
with 255, but 255 could appear in the second or third octet.
