3) From the given subnet, we can also calculate the IP range of a particular network. Thus the network ID is 10 and the host ID is 20.12.2. IP's above 224.0.0.0 are used for both multicast and experimental purposes. The bits corresponding to all 0’s of the subnet mask is the host ID. In this IP address we have only 16 bits for host. The subnet mask is fixed 255.255.0.0 for a classfull class B IP address. The range of ip address in a class B network is from 128.0.0.0 to 191.255.255.255. A classful network is an obsolete network addressing architecture used in the Internet from 1981 until the introduction of Classless Inter-Domain Routing (CIDR) in 1993. Before going for subnetting for class B network we recommend to read the previous article of subnetting for class C network. For this purpose, the IANA has reserved the following three address blocks for private internets: Map of the prototype Internet in 1982, showing 8-bit-numbered networks (ovals) only, interconnected by routers (rectangles). RFC 1918 requests that organizations make use of the private Internet address space for hosts that require IP connectivity within their enterprise network, but do not require external connections to the global Internet.
