Lec15 Network Pdf Computer Network Network Topology ¡ ip addresses (and possibly port numbers) of ip datagrams are replaced at the boundary of a private network ¡ enables hosts on private networks to communicate with hosts on the internet ¡ run on routers that connect private networks to the public internet. Topic 5 ip addressing and subnetting free download as pdf file (.pdf), text file (.txt) or read online for free. the document covers ip addressing and subnetting, focusing on ipv4 addressing schemes, classful addressing, and the importance of valid ip addresses.
Lec9 Networks Pdf Computer Network Transmission Medium To introduce the concept of an address space in general and the address space of ipv4 in particular. to discuss the classful architecture and the blocks of addresses available in each class. to discuss the idea of hierarchical addressing and how it has been implemented in classful addressing. Each device on an ip network requires 3 different pieces of information in order to correctly communicate with other devices on the network: an ip address, a subnet mask, and a broadcast address. Address class early in the development of ip, the iana (internet assigned numbers authority) designated five classes of ip address: a, b, c, d, and e. these classes were identified based on the pattern of high order bits (the high value bits at the beginning of the first octet). 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.

Ip addressing addresses need to be globally unique, so they are hierarchical another reason for hierarchy: aggregation reduces size of routing tables at the expense of longer routes.
