Description

IP address identifies both host and thenetworkwhere that host resides; the IP address class system givesa clue todistinguish both network and host portion of the address.But theaddress class system is too inflexible to do the job alone.In thereal world, networks come in all sizes, and many networksaredivided into smaller units. Furthermore, the world is runningout ofclass-level networks. ISPs and network admins need aflexible meansto subdivide a class-level network so that datagramsarrive atrouters serving a smaller address space. Subnetting letsyou breakthe network into smaller units called subnets. Theconcept of asubnet originally evolved around the address classsystem, andsubnetting is best explained in the context of Class A,B and Cnetworks.
Find it difficult to calculate and manage networks andsubnets?SubnetCalc is a tool to help you with it! With just theIPv4address, you can find what you need for a network! It isalsointended to be a teaching tool. Not more than 1024 subnetsareviewable.
