== Network address and logical address==

The term ”’network address”’ sometimes refers to [[logical address]], i.e. [[network layer]] address such as the [[IP address]], and sometimes to the first address (the base address) of a [[classful address]] range to an organization.

The term ”’network address”’ sometimes refers to [[w:logical address|logical address]], i.e. [[w:network layer|network layer]] address such as the [[w:IP address|IP address]], and sometimes to the first address (the base address) of a [[w:classful address|classful address]] range to an organization.

Computers and devices that are part of internetworking network such as the Internet all have a logical address. The network address is unique to that device and can either be [[Dynamic Host Configuration Protocol|dynamically]] or statically configured. This address allows the device to communicate with other devices connected to the network. The most common network addressing scheme is IPv4. The IPv4 network address consists of a 32 bit address divided into 4 [[Octet (computing)|octets]] and a subnet mask of like size. In order to facilitate the [[routing]] process the address is divided into two pieces, the network address and the host address. This works much like a postal address where the network address would represent the city and the host address would represent the street address. The subnet mask is used in conjunction with the network address to determine which part of the address is the network address and which part is the host address.
