A subnetwork, or subnet, is a logical subdivision of an IP network.: 1, 16  The practice of dividing a network into two or more networks is called subnetting...

significant bits are the network prefix, which identifies a whole network or subnet, and the least significant set forms the host identifier, which specifies...

security a screened subnet refers to the use of one or more logical screening routers as a firewall to define three separate subnets: an external router...

EDNS Client Subnet (ECS) is an option in the Extension Mechanisms for DNS that allows a recursive DNS resolver to specify the subnetwork for the host or...

a subnet is a generalization of the concept of subsequence to the case of nets. The analogue of "subsequence" for nets is the notion of a "subnet". The...

local broadcast address and the all-ones host address of each subnet is that subnet's directed broadcast address. The directed broadcast address for...

networks:: 4  In practice, it is common to subdivide these ranges into smaller subnets. In April 2012, IANA allocated the 100.64.0.0/10 block of IPv4 addresses...
