This document specifies the operation the IPv6 Internet with mobile computers. Each mobile node is always identified by its home address, regardless of its current point of attachment to the Internet. While situated away from its home, a mobile node is also associated with a care-of address, which provides information about the mobile node’s current location. IPv6 packets addressed to a mobile ...

IPv6 was designed to replace the existing Internet Protocol, that is, IPv4. The main advantage of IPv6 over IPv4 is the vastness of address space. In addition, various improvements were brought to IPv6 to address the drawbacks in IPv4. Nevertheless, as with any new technology, IPv6 suffers from various security vulnerabilities. One of the vulnerabilities discovered allows Denial of Service Atta...

This paper gives an overview of the issues related to the QoS mechanisms under IPv6 and the transition of applications to the new Internet protocol. We describe the implementation and testing of a QoS service on IPv6 networks, which is based on the DiffServ architecture (expedited forwarding) and provides strict priorities to packets that are produced from real time applications. The service wa...

This document specifies the operation of mobile computers using IPv6. Each mobile node is always identified by its home address, regardless of its current point of attachment to the Internet. While situated away from its home, a mobile node is also associated with a care-of address, which provides information about the mobile node’s current location. IPv6 packets addressed to a mobile node’s ho...

The current generation of IP, version 4 (IPv4), has been in use for more than 20 years since its inception in 1980 and has supported the Internet's rapid growth during that time. IPv4 has proven to be robust, easily implemented and interoperable. This is a tribute to its initial design. However, the current Internet has grown much bigger than was anticipated. The Internet Engineering Task Force...

IPv6 is the replacement for the Internet’s incumbent protocol, IPv4. Although exhaustion of the IPv4 address space is now imminent there has been no meaningful uptake of IPv6 since its standardisation in 1998. Data from a national survey of the top 1,000 IT user organisations in Australia are analysed, revealing that they have made little or no preparation for IPv6. This creates the potential f...

Much work has been done on IPv6 standards and many IPv6 testbeds have been deployed. However, little is known about the performance of the real IPv6 Internet, especially from the perspective of end users. In this paper, we perform a case study of current IPv6 performance from CERNET1. We propose an active measurement methodology, which analyzes the traces of file transference from IPv4/IPv6 dua...

Global IPv6 deployment was slower than originally expected. As IPv4 address exhaustion approaches, IPv4 to IPv6 transition issues become more critical and less tractable. Host-based transition mechanisms used in dual-stack environments cannot meet all transition requirements. Most end users are not sufficiently expert to configure or maintain host-based transition mechanisms. CarrierGrade NAT (...

The actual transition from IPv4 to IPv6 requires network administrators to become aware of the next generation protocol and the associated risk problems.Due to the scale and complexity of current internet architecture how to protect from the existing investment and reduce the negative influence to users and service providers during the transition from IPv4 to IPv6 is a very important future top...

The adoption of the Internet Protocol in mobile and wireless technologies has considerably increased the number of hosts that can potentially access the global Internet. IPv6 is considered the long term solution for the IPv4 address shortage problem, but the transition from IPv4 to IPv6 is supposed to be very gradual. Therefore, there will be a long time during which both protocol versions will...
