Understanding TCP/IP addressing and subnetting basics

Dec 12, 2018 IP Subnet Calculator In IPv6, the network prefix performs a similar function as the subnet mask in IPv4, with the prefix length representing the number of bits in the address. Prior to the introduction of CIDR, IPv4 network prefixes could be directly obtained from the IP address based on the class (A, B, or C, which vary based on the range of IP addresses they Online IP Subnet Calculator The subnet calculator allows a subnet ID to have its final octet equal to the final octet of its subnet mask - for example, a class C network address of with a subnet mask of is permitted. The above is generally accepted as being 'normal', however, certification students should keep in mind that, in some Subnet Calculator for IP Addresses and Subnetting ONLINE!

In IPv4, the subnet mask is 32 bits and consists of four 8-bit octets. The address: subnet mask means that the subnet is a range of IP addresses from - The prefix-length in IPv6 is the equivalent of the subnet mask in IPv4.
