network identification (net-id)

  1. The term network ID(net-id) is commonly used to authenticate network devices, servers and portals; as well as content, applications, user data and contact information.
  2. In addition, the IP protocol knows the designation network identification (netid). This is the classic classification of IP addresses. Classical IP addresses were divided into address classes and consisted of the network identification (netid) and the host identification( host-id). There were three address classes with a fixed mapping between network addresses and host addresses.

    classes These were address classes A, B, and C with 128 (7 bit), 16,384 (14 bit), and 2,097,152 (21 bit) network addresses. This inflexible address class scheme has been eliminated with Classless Interdomain Routing( CIDR) for IPv4 addresses offers leeway for up to 4,294,967,296 (32 bit) network identifiers. The same applies to IPv6 addresses, which are also structured according to CIDR and even represent an address range of 128 bits.
