ES-3148 User’s Guide 317 A PPENDIX B IP Addresses and Subnetting This appendix introduces IP addresses, IP address classes and subnet masks. Y ou use subnet masks to subdivid e a network in to smaller logical networks. Introduction to IP Addresses An IP address has two parts: the network numb er and the host ID.
ES-3148 User’s Guide 318 The following table shows the network number and host ID arrangement for classes A, B and C. An IP address with host IDs of all zeros is the IP address of the n etwork (192.168. 1.0 for example). An IP address with host IDs of all ones is the broadcast address for that network (192.
ES-3148 User’s Guide 319 Subnet Masks A subnet mask is used to dete rmine which bits are part of th e network number , and which bits are part of the host ID (using a logical AND operation). A subnet mask has 32 bits. If a b it in the subnet mask is a “1” then the correspondi ng bit in the IP address is part of the n etwork number .
ES-3148 User’s Guide 320 The first mask shown is the class “C” natural m ask. Normally if no mask is specified it is understood that the natura l mask is being used. Example: T wo Subnet s As an example, you have a class “C” address 1 92.168.
ES-3148 User’s Guide 321 Host IDs of all zeros represent the subnet itsel f and host IDs of all ones are the broadcast address for that subnet, so the actual number of hosts available on each subnet in the example above is 2 7 – 2 or 126 h o sts for each subnet.
ES-3148 User’s Guide 322 Example Eight Subnet s Similarly use a 27-bit mask to create eight subnets (000, 001, 010 , 01 1, 100, 101, 1 10 and 111 ) . Subnet Address: 192.1 68.1.0 Low est Host ID: 192.168.1.1 Broadcast Address: 192.168.1.63 Highest Host ID: 192.
