Ip Fundamentals Pdf Pdf Osi Model Communications Protocols 2.1 1 ip address fundamentals free download as pdf file (.pdf), text file (.txt) or read online for free. ip addresses are unique numbers that allow systems to communicate over a network. an ip address has two parts the network portion and the host portion. Table a 1 describes how ip address classes are organized. you can always tell what class an address is by looking at the first octet and comparing it to the chart above. for instance, the address at the top of this appendix has 198 as the first octet, so it is class c.
1 2 2 Ip Addressing Pdf Ip Address Domain Name System • efficient for large (unknown) group –use special broadcast ip address. • ip addresses have a special broadcast address • class .vs. classless addressing. • internet assigned numbers authority (iana). Let’s walk through a simple host to host packet delivery example and then understand how the structure of ip addresses helps scale routing. why ip addresses? a mac address has no structure, so it tells a switch the identity (who) of the destination interface but not its location (where). • ip addresses are referred to as public or private • public ip is assigned to customer by isp • private ip is assigned by local it admin or hardware itself • ip runs over ethernet and several other hardware interfaces. In order to provide the flexibility required to support different size networks, the designers decided that the ip address space should be divided into three different address classes class a, class b, and class c.

Packets in a connectionless network all carry the full destination address on every packet. packets are simply sent into the network, relying on each intermediate. N simple ip ¡ all hosts on the same network must have the same network number n assumptions ¡ subnets are close together n look like one network to distant routers n idea ¡ take a single ip network number ¡ allocate the ip addresses to several physical networks (subnets) n subnetting ¡ all hosts on the same network must have the same. An ip address is a logical identifier for a computer or device on a network. the key feature of ip addresses is that they can be routed across networks. university of babylon college of information technology information network dept. Ip addresses are 32 bit long, hierarchical addressing scheme. routers facilitate communication within this internet work. it decides how to send packets within the network so that they arrive at their destination.
