The next-generation Internet Protocol, initially known as IP Next Generation (Ipng), and then later as IPv6, has been developed by the Internet Engineering Task Force (IETF) to replace the current Internet Protocol (also known as IPv4). To enable the integration of IPv6 into current networks, several transition mechanisms have been proposed by the IETF IPng Transition Working Group. This work e...

The Dynamic Host Configuration Protocol for IPv6 (DHCP) enables DHCP servers to pass configuration parameters such as IPv6 network addresses to IPv6 nodes. It offers the capability of automatic allocation of reusable network addresses and additional configuration flexibility. This protocol is a stateful counterpart to "IPv6 Stateless Address Autoconfiguration" [20], and can be used separately o...

Momentum for IPv6 transition is on the rise, and many transition tools and techniques are available to ISPs, enterprise networks, and unmanaged networks. T he rationale for introducing IPv6 is beginning to sway many network providers in commercial and research environments. 1 Among IPv6's unique benefits over IPv4 are increased address space, simpler " plug and play, " network security, and imp...

Middleboxes such as firewalls are an important aspect for a majority of IP networks today. Current IP networks are predominantly based on IPv4 technology, and hence various firewalls as well as Network Address Translators (NATs) have been originally designed for these networks. Deployment of IPv6 networks is currently work in progress. Given the fact that Mobile IPv6 is a recent standard, most ...

Industry stakeholders and Internet experts generally agree that IPv6-based networks in many ways would be technically superior to IPv4-based networks. The redesigned header structure in IPv6, including new flow labels, and the enhanced capabilities of the new protocol could provide significant security benefits to Internet users, network administrators, and applications developers. However, the...

IPv6 protocol, which should replace the actual IPv4 protocol, brings many new possibilities and improvements considering simplicity, routing speed, quality of service and security. In comparison to IPv4, IPv6 improves mechanisms for assuring a secure and confidential transfer of information. Despite these improvements, network security remains a very important issue since there are some securit...

We measure YouTube content delivery over IPv6 using ⇠100 SamKnows probes connected to dual-stacked networks representing 66 different origin ASes. Using a 34-months long (Aug 2014-Jun 2017) dataset, we show that success rates of streaming a stall-free version of a video over IPv6 have improved over time. We show that a Happy Eyeballs (HE) race during initial TCP connection establishment leads t...

This document specifies Mobile IPv6, a protocol that allows nodes to remain reachable while moving around in the IPv6 Internet. 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 curr...

The IVI is a prefix-specific and stateless address mapping mechanism for "an IPv6 network to the IPv4 Internet" and "the IPv4 Internet to an IPv6 network" scenarios. In the IVI design, subsets of the ISP’s IPv4 addresses are embedded in the ISP’s IPv6 addresses, and the hosts using these IPv6 addresses can therefore communicate with the global IPv6 Internet directly and can communicate with the...
