ES-4024A User’s Guide IP Subnetting 269 A PPENDIX B IP Subnetting IP Addressing Routers “route” based on the network number . The router that delivers the data packet to the correct destination host uses the host ID. IP Classes An IP address is made up of four octets (ei ght bits), wri tten in dotted decimal notation, for example, 192.
ES-4024A User’s Guide 270 IP Subnetting Since the first octet of a class “A” IP address must contain a “0”, the first octet of a class “A” address can have a valu e of 0 to 127. Similarly the first octet of a class “B” must begi n with “10”, therefore the first octet of a class “B” address has a valid range of 128 to 191.
ES-4024A User’s Guide IP Subnetting 271 Since the mask is always a continuous number of ones begin ning from the left, fo llowed by a continuous number of zeros for the remainder of the 32 bit mask, you can si mply specify the number of ones instead of writing the value of each octet.
ES-4024A User’s Guide 272 IP Subnetting Note: In the following chart s, shaded/bolded last octet bit values indicate host ID bit s “borrowed” to form network ID bit s. The number of “borrowed” host ID bits determines the number of sub nets y ou can have.
ES-4024A User’s Guide IP Subnetting 273 Example: Four Subnet s The above exampl e illustrated using a 25-bit subne t mask to divide a class “C” address space into two subnets. Similarly to divide a class “C” address into four subnets, you need to “borrow” two host ID bits to give four possible combinations of 00 , 01, 10 and 1 1.
ES-4024A User’s Guide 274 IP Subnetting Example Eight Subnet s Similarly use a 27-bit mask to create 8 subnets (001 , 010, 01 1, 100, 101, 1 10). The following table shows class C IP ad dress last octet values for each subnet. The following table is a summary for class “C” subnet planning.
ES-4024A User’s Guide IP Subnetting 275 Subnetting With Class A and Class B Networks. For class “A” and class “B” addresses the subnet ma sk also determines which bits are part of the network number and which are part of the host ID.
