Network Management Homework: IPv6 Transition and Subnetting Analysis

This document presents solutions to a network management assignment focusing on the transition from IPv4 to IPv6 and subnet design. The solution to question 4 discusses the methods for IPv6 transition, including the dual stack router method and tunneling method, enabling companies to maintain existing infrastructure while achieving IPv6 connectivity. Question 5 addresses the design of sub-networks for four different offices using the IP address 206.206.155.0/24, detailing the allocation of address ranges, subnet masks, and assignable IP address ranges for each office. The solution includes a table summarizing the subnet names, required sizes, allocated sizes, address masks, decimal masks, assignable ranges, and broadcast addresses. The document references relevant research papers that support the solutions provided.

Answer to question 4:
The transition of the network from the IPv4 to the IPv6 requires addressing to various
network parameters. This also requires adoption of new techniques like the dual stack router
method or the tunneling method. This will enable the company to retain their original
infrastructure and get IPv6 connectivity. In the dual stack method, a router is fixed at the
topology which can communicate with both the IPv6 and the IPv4 traffic (Wu et al., 2013). In a
similar way, the existing network can also support the tunneling mechanism. This involves
setting up of transit networks in the middle of the communication lines, which converts the IPv4
traffic to IPv6 from the sender and then transmits it. Additionally, this is also used to convert the
IPv6 traffic to IPv4 in the receiver side. These methods can be used to adopt IPv6 in the existing
networks.
Answer to question 5:
For the IP address 206.206.155.0/24, the network includes designing of various sub-
networks to support the four different offices. This will be achieved by dividing the address
among multiple subnet ids. The possible ranges that can be applied in each of the offices are
listed in the table.
