Appendix B Network, Routing, Firewall, and Basics This chapter provides an overview of IP networks, routing, and networking. Related Publications As you read this document, you may be directed to various RFC documents for further information. An RFC is a Request For Comment (RFC) published by the Internet Engineering Task Force (IETF), an open organization that defines the architecture and operation of the Internet.
Reference Manual for the 108 Mbps Wireless Firewall Router WGT624 v3 Routing Information Protocol One of the protocols used by a router to build and maintain a picture of the network is the Routing Information Protocol (RIP). Using RIP, routers periodically update one another and check for changes to add to the routing table. The WGT624 v3 wireless router supports both the older RIP-1 and the newer RIP-2 protocols. Among other improvements, RIP-2 supports subnet and multicast protocols.
Reference Manual for the 108 Mbps Wireless Firewall Router WGT624 v3 Class A Network Node Class B Network Node Class C Network Node 7261 Figure 7-1: Three Main Address Classes The five address classes are: • Class A Class A addresses can have up to 16,777,214 hosts on a single network. They use an eight-bit network number and a 24-bit node number. Class A addresses are in this range: 1.x.x.x to 126.x.x.x. • Class B Class B addresses can have up to 65,354 hosts on a network.
Reference Manual for the 108 Mbps Wireless Firewall Router WGT624 v3 This addressing structure allows IP addresses to uniquely identify each physical network and each node on each physical network. For each unique value of the network portion of the address, the base address of the range (host address of all zeros) is known as the network address and is not usually assigned to a host.
Reference Manual for the 108 Mbps Wireless Firewall Router WGT624 v3 Subnet addressing allows us to split one IP network address into smaller multiple physical networks known as subnetworks. Some of the node numbers are used as a subnet number instead. A Class B address gives us 16 bits of node numbers translating to 64,000 nodes. Most organizations do not use 64,000 nodes, so there are free bits that can be reassigned. Subnet addressing makes use of those bits that are free, as shown below.
