A subnet is a division of an IP network ( internet protocol cortege ), where an IP network is a hardened of communications protocols used on the Internet and other alike networks. It is normally known as TCP/IP ( Transmission Control Protocol/Internet Protocol ) .
The act of dividing a network into at least two separate networks is called subnetting, and routers are devices that allow traffic exchange between subnetworks, serving as a forcible boundary. IPv4 is the most common net addressing computer architecture used, though the use of IPv6 has been growing since 2006.

An IP address is comprised of a network number ( routing prefix ) and a rest field ( host identifier ). A rest field is an identifier that is specific to a given host or net interface. A routing prefix is often expressed using Classless Inter-Domain Routing ( CIDR ) note for both IPv4 and IPv6. CIDR is a method acting used to create singular identifiers for networks, vitamin a well as individual devices. For IPv4, networks can besides be characterized using a subnet mask, which is sometimes expressed in dot-decimal note, as shown in the “ Subnet ” playing field in the calculator. All hosts on a subnetwork have the same network prefix, unlike the host identifier, which is a singular local anesthetic recognition. In IPv4, these subnet masks are used to differentiate the network number and host identifier. In IPv6, the network prefix performs a similar officiate as the subnet mask in IPv4, with the prefix length representing the numeral of bits in the address .
anterior to the insertion of CIDR, IPv4 net prefixes could be directly obtained from the IP address based on the class ( A, B, or C, which vary based on the range of IP addresses they include ) of the address and the net mask. Since the introduction of CIDRs, however, assigning an IP address to a network interface requires both an address and its network mask .
