HEX
Short for hexadecimal refers to the base-16 number
system, which consists of 16 unique symbols: the

Internet address
To participate in Internet communications and on Internet
Protocol-based networks, a node must have an Internet
address that identifies it to the other nodes. All Internet
addresses are IP addresses
IP
Internet Protocol is the standard that describes the layout
of the basic unit of information on the Internet (the
packet
) and also details the numerical addressing format
used to route the information. Your Internet service
provider controls the IP address of any device it connects
to the Internet. The IP addresses in your network must
conform to IP addressing rules. In smaller LANs, most
people will allow the DHCP function of a router or
gateway to assign the IP addresses on internal networks.
IP address
IP address is a 32-binary digit number that identifies
each sender or receiver of information that is sent in
packets across the Internet. For example 80.80.80.69 is
