The internet has been using its protocol, IPv4, for more than a quarter of a century. The internet saw its deployment found the tipping point in early 1990s with the popularity of World Wide Web. This fast pace development, however, creates problems for IPv4:
Exhaustion of IP Address
Routing table explosion
Proliferation of Network Address Translation
Lack of Security
A new version of the Internet Protocol, IPv6, has been developed and is likely to replace IPv4. IPv6 has been developed to solve the problems regarding to IPv4 and also new features are designed to supposedly enhance network traffic.
It is the time to have a transition from IPv4 to IPv6. The current internet age is running in its transition phase to new generation internet addressing. In this perspective, this research thesis will try to explore about how to migrate the network into IPv6 only Operation properly. Hence this thesis is focused on the following:
- comparative study on different transition mechanisms
- analyze the problems and difficulties to be faced during transition
- experimental verification of IPv6 only operation, a case study with respect to SOI network
Prospective analysis after gathering information from people working in Nepalese ISPs in order to address some of the aspects of upgrading.
