The development of Internet Protocol version 6 (IPv6) came with a larger header size 40-Byte compared the 20-Byte 4 (IPv4) which would have made IPv6 protocol bottleneck in data transmission over global network. Practically, given same user transmitted physical-layer network medium both IPv4-enabled and IPv6-enabled networks, speed be slower setup to IPv4 scenario, but bandwidth is optimized in...

This practitioner paper provides an introduction to investigating IPv6 networks and systems. IPv6 addressing, packet structure, and supporting protocols are explained. Collecting information from IPv6 registries and databases such as Whois and DNS is demonstrated. Basic concepts and methods relevant for digital forensic investigators are highlighted, including the forensic analysis of IPv6 enab...

The Internet Protocol version 6 (also known as IPv6) has been developed to replace the current IPv4 protocol. Various operating systems running at end-systems now support IPv6 protocol stacks and network infrastructures (hosts, routers) are currently being deployed to support IPv6 features. IPv6 stacks on end-systems constitute an important component in the migration and adoption of IPv6. To in...

This specification defines the addressing architecture of the IP Version 6 protocol [IPV6]. The document includes the IPv6 addressing model, text representations of IPv6 addresses, definition of IPv6 unicast addresses, anycast addresses, and multicast addresses, and an IPv6 node’s required addresses. draft-ietf-ipngwg-addr-arch-v2-02.txt [Page 1] INTERNET-DRAFT IPv6 Addressing Architecture July...

Though the popular Cisco NetFlow is widely used for flow-level traffic measurement in IPv4 networks, it is not suitable for IPv6 networks because of the fixed flow structure that cannot carry IPv6-related information. Therefore, the IETF IP Flow Information eXport (IPFIX) standard that employs the flexible flow template structure has been recently proposed to support various flow-level traffic ...

While some IPv6-enabled Web sites such as Google require an explicit opt-in by IPv6-enabled clients before serving them over the IPv6 protocol, we quantify performance implications of unilateral enabling of IPv6 by a Web site. In this approach, the Web site enables dual-stack IPv4/6 support and resolves DNS queries for IPv6 addresses with the IPv6 addresses of its Web servers, and legacy DNS qu...
