IP Addressing IP Addressing By subdividing TCP/IP networks into  smaller groupings called subnets, the  administration of a TCP/IP network can be  as centralized or as decentralized as the  needs of a particular organization might  dictate.  The largest TCP/IP network in the world,  which is “owned” and administered by  hundreds and thousands of separate  entities, is the  Internet .

IP Addressing IP Addressing For any computer or  host  to communicate on a  TCP/IP network, it must be configured with a  valid  IP address . Each IP address consists of two components: network address  — This portion of the IP address  is shared by all TCP/IP hosts on a particular  network or subnet. host address  — This comprises the portion of the  IP address that is unique to a particular computer or  host.  Both combined form a unique IP address across  an entire TCP/IP network.

IP Addressing IP Addressing In addition to the IP address, each TCP/IP host  must be configured with the following: subnet mask —  Used to identify which network  the TCP/IP host resides on by defining where the  network address stops and the host address  begins. default gateway —  Allows a host to  communicate with devices that reside on a  remote network or location.  You don’t need a default gateway if it is does not  need to communicate outside of the host’s own  subnet .

IPv4 Addressing IPv4 Addressing The most commonly used version used today. Based on 32-bits (four bytes, or octets). 2 32  (4,294,967,296) possible addresses.  Some of the possible addresses are reserved  IPv4 addresses are commonly represented  using what is called  dotted-decimal notation , in  which the decimal value of each byte is shown,  using periods to separate the bytes: 10.27.3.1 192.1.120.84 192.5.18.102
