Prestige 2002 Series User’s Guide 90 Appendix C IP Subne tting 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.
Prestige 2002 Series User’s Guide Appendix C IP Subnetting 91 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.
Prestige 2002 Series User’s Guide 92 Appendix C IP Subne tting Divide the network 192.168.1. 0 into two separate subnets by converting one of th e host ID bits of the IP address to a network number bit. The “ borrowed” host ID bit can be either “0” or “1” thus giving two subnets; 19 2.
Prestige 2002 Series User’s Guide Appendix C IP Subnetting 93 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.
Prestige 2002 Series User’s Guide 94 Appendix C IP Subne tting 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.
Prestige 2002 Series User’s Guide Appendix C IP Subnetting 95 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.
