Short for hexadecimal refers to the base-16 number

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
an IP address. When you “call” that number, using any
