EE 281 Lecture 7: IP subnetting supernetting
Document Summary
Ipv4 is a 32 bit address , with 4 octets, while ipv6 is a 128 bit address. It can be classified into 5 types : In case of binary notations examine the prefixes for determining the classes. These are fixed for the private ip addresses. It is a process of breaking a large network into smaller segments, coz maintaining a larger network is a tedious task as well as security concerns are more, so for this reason subnetting is used, For determination of an ip that it belongs to which network part, we can it has to be anded with the subnet, the and of both results in the nid part. In variable length subnet masking, we can divide the network into odd number of parts, for this choose either 0/1 for a network the for the other two choose 11,10 or 00,01.
