Address Management in IPv6 Network

In this we tend to use a plan of Subnetting for sophistication 'C' address to scale back the address area. We tend to purposed "Aggregate Variable Length Subnet Masking exploitation IP4" with the assistance of fastened Length Subnet Masking, Variable Length Subnet Masking and combination fastened length Subnet Masking. scientific discipline Addresses are at a premium, therefore we tend to minimize the whole scientific discipline usages. Here, we tend to ar operating with the Cisco Packet Tracer and introduced the management of address area and key management in IPv6 network. In unicast and multicast IPv6 networks key management is one among the key security problems. To realize secure communications in such networks reliable and competent key management theme ought to be obligatory and enforced, Whenever a brand new node is accepted to affix or leave the network, a brand new key ought to be generated and distributed to each nodes within the multicast group. Inadequately, this approach will increase the amount of keys transmitted (communication cost) of the key management, whereas variety of algorithms has been projected to handle this issue, most of them have severely affected the computation price (i.e., range of key coding, decryption, and derivation) of the key management. By concentrating on communication and computation prices, we tend to provide prominence to the chance of addressing the each prices while not having to sacrifice one for the sake of the opposite. during this paper, we tend to propose a light-weight key management theme for IPv6 networks, that is capable of reducing each communication and computation prices. The performance analysis demonstrates the potency of our projected methodology as compared with the present ones in reducing such prices, whereas at identical time maintaining each forward and backward securities.
