ES-2108/ES-2108-G User’s Gu ide 206 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.
ES-2108/ES- 2108-G Use r’s Guide IP Subnetting 207 Since the mask is always a continuous number of ones begin ning from the left, followe d 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-2108/ES-2108-G User’s Gu ide 208 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-2108/ES- 2108-G Use r’s Guide IP Subnetting 209 Example: Four Subnet s The above exampl e illustrated using a 25-bit subne t mas k to divide a class “C” address space into two subnets.
ES-2108/ES-2108-G User’s Gu ide 210 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.
