A host can be a computer, server, printer, any device that is connected to the network. IP addresses are similar to phone numbers in that each identifies a unique host on a network as a phone number identifies a single phone on the phone network.
TCP/IP and Subnet Masking
As each phone number is divided into parts Area Code Identifies the network the phone is on. In this case it represents a phone on the Chicago network. IP addresses have two main parts.
The Network and the Host parts. Subnet Masks The subnet mask identifies the network and hosts portions of the IP address. In Binary 1,0 the subnet mask is very simple.
There are 4 octets to the subnet mask just as there are to an IP address. In the subnet mask the value of 1 one represents the network portion and 0 zero represents the host portion.
There are D and E classes for later discussion. Even though most IP addresses are written in Dotted Decimal notation. The Class of address is determined by the first Octet.
