Table 1-1 represents traditional subnetting of a Class B network Standards- based practice for using all definable subnets. Subnets are included in Tables 1-1 and 1-2 per the current, The number of subnetting bits and the resulting network, broadcastĪddress, and host addresses. The number of bits used for subnet masking. The number of available network and host addresses are derived from The CIDR representation form (/xx) and the Decmial equivalents. The following table lists the variable length subnets from 1 to 32, This document itemizes the potential values for IPv4 subnets.Īdditional information is provided for Hex and Decmial values,Ĭlassfull equivalants, and number of addresses available within the Misinterpreted leading to confusion regarding proper subnetting. The previously mentioned RFCs comprise the available guidelines forĬreating subnetted networks, however they have occassionaly been
RFC-1123 has resulted in larger and more complex network subnetting. The growth of networking since the time of STD 5, RFC 0950 and STD 3, This memo is intended as an informational companion to Subneting RFC This table includes subnettingįor Class A, B, and C networks, as well as Network IDs, host rangesĪnd IP broadcast addresses with emphasis on Class C subnets. This memo clarifies issues surrounding subnetting IP networks by This memoĭoes not specify an Internet standard of any kind. This memo provides information for the Internet community.
