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...

for a subnet mask, the router assumes that all subnetwork addresses within the same Class A, Class B, or Class C network have the same subnet mask as...

into subnets began in 1985 with the publication of RFC 950. This division was made more flexible with the introduction of variable-length subnet masks...

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...

This indicates that the gateway to reach the corresponding destination subnet is unspecified. This generally means that no intermediate routing hops are...
