It allocates IP addresses in a more flexible manner as compared to the original system of Internet Protocol (IP) address classes. In this way, it increases the number of available IP addresses with extensive use of <a href=\"https:\/\/www.whizlabs.com\/blog\/nat-gateway\/\" target=\"_blank\" rel=\"noopener noreferrer\">NAT (Network Address Translation)<\/a>.<\/p>\n<p style=\"text-align: justify\">By providing a new, more efficient way to allocate network addresses, CIDR has reduced the issue of wasted address space in the routers. With CIDR, one entry in the routing table entry represents a combination of networks existing in the forward path. This network aggregation in a single address is known as Supernet.<\/p>\n<h4 style=\"text-align: justify\"><b>CIDR Notation<\/b><\/h4>\n<p style=\"text-align: justify\">CIDR IP addresses can be described as consisting of two groups of bits. The most significant group of bits denotes the prefix i.e., a network address that is used for the identification of a network or sub-network. The least significant group of bits is known as host identifier that determines the total number of bits in the address. It is used to signify the device on the work that will receive incoming information packets.<\/p>\n<p style=\"text-align: justify\">For example, consider the following CIDR Notation<\/p>\n<p style=\"text-align: justify\">182.0.1.2\/28<\/p>\n<p style=\"text-align: justify\">Here, the prefix is \u2013 182.0.1.2, and<\/p>\n<p style=\"text-align: justify\">The total number of bits in this address is 28.<\/p>\n<h4 style=\"text-align: justify\"><b>CIDR Block<\/b><\/h4>\n<p style=\"text-align: justify\">The prefix, first group of bits in the notation allows you to group the multiple blocks of network addresses into a single routing network. CIDR blocks share the first group of bits (the binary representation of the network addresses). The blocks are also identified using same decimal dot notation system as IPv4 addresses.<\/p>\n<p style=\"text-align: justify\">For example, a CIDR block is shown below<\/p>\n<p style=\"text-align: justify\">10.0.1.0\/24<\/p>\n<p style=\"text-align: justify\">Here \/24 signifies the total number of 1\u2019s bits in the routing mask (network mask).<\/p>\n<p style=\"text-align: justify\">This IP address can be shown as below in the binary format:<\/p>\n<p style=\"text-align: justify\">11111111.11111111.11111111.00000000<\/p>\n<p style=\"text-align: justify\">Here the first 24 bits are marked as 1.<\/p>\n<p style=\"text-align: justify\">It would be equivalent to a network mask of 255.255.255.0<\/p>\n<p style=\"text-align: justify\">Note that the network addresses that have the identical prefix and the same number of bits, always belong the same block. Also, the large and small blocks can be distinguished by the length of the prefix.<\/p>\n<h2 style=\"text-align: justify\"><span class=\"ez-toc-section\" id=\"Calculating_the_Network_Mask\"><\/span><b>Calculating the Network Mask<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify\">Let\u2019 say that we have given a notation of \/20 as the mask, how can we calculate the network mask<\/p>\n<p style=\"text-align: justify\">We can do this with the help of the below table notation.<\/p>\n<table border=\"1\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td width=\"78\" valign=\"top\" style=\"text-align: center\">128<\/td>\n<td width=\"78\" valign=\"top\" style=\"text-align: center\">64<\/td>\n<td width=\"78\" valign=\"top\" style=\"text-align: center\">32<\/td>\n<td width=\"78\" valign=\"top\" style=\"text-align: center\">16<\/td>\n<td width=\"78\" valign=\"top\" style=\"text-align: center\">8<\/td>\n<td width=\"78\" valign=\"top\" style=\"text-align: center\">4<\/td>\n<td width=\"78\" valign=\"top\" style=\"text-align: center\">2<\/td>\n<td width=\"78\" valign=\"top\" style=\"text-align: center\">1<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"text-align: justify\">For a mask of \/20, the equivalent binary format would be as follows<\/p>\n<p style=\"text-align: justify\">11111111.11111111.11110000.<b>11111111<\/b><\/p>\n<p style=\"text-align: justify\">From the third octet, e can see that there are 4 leading 1\u2019s.
