IPv6 Panel Discussion IETF 54 Plenary Brian D. Zill [email protected] Our Background in v6 IPv6 stack implementer Implementation started in 1996 in Microsoft Research (by myself and Richard Draves) Multiple web releases in subsequent years, targeting NT 4 and (later) Windows 2000. Implementation moved to Windows Networking group in 2000. Couple of web releases targeting Windows 2000. Shipped IPv6 stack in Windows XP. More background Public 6to4 relay operator Established first relay. OS services developer Internet Explorer, ftp, telnet, RPC were all IPv6−enabled in XP release. IPv6−enabled IIS, File and Print sharing, Media Server, more, are under development for this years .NET Server release. Implemented, used Stateless address auto−config (It just works). DDNS registration of AAAA records Temporary (aka privacy) addresses Off by default in server product. Site−local address support Needed scoped address support for link−local. Additional work for site−locals was small. Anycast especially useful for service discovery. Customers like site boundary feature. Implemented, used ISATAP for automatic tunneling inside corporate network environments Router Discovery impacted by DNS config. 6to4 for automatic tunneling in the Internet portproxy a cross−protocol TCP port forwarder. Implemented, used less 6over4 ISATAP serves similar purpose, but doesnt require multicast−enabled IPv4 network. Configured tunnels 6to4 is easier to set up and use. IPsec Current IPv6 implementation doesnt yet support IKE, requires manual keying. We consider this important, plan to fully support IPsec for IPv6 in future release. Prototype implementations NAT−PT, SIIT Mobile IPv6 Not implemented Stateful address autoconf (via DHCPv6) DSTM A6 / DNAME Routing protocols / Router renumbering Considering / Underway Multicast DNS Prefix delegation Not clear which solution to implement. PPP support Node information queries Address to name translation. Teredo V4 mapped addresses Specs to augment/revisit Site Prefixes in Neighbor Discovery Draft expired, needs reissue and update Default Router Preferences, More− Specific Routes, and Load Sharing Draft needs approval and IANA assignment Fun Stuff Direct Play New Peer−to−peer apps.

Global Mobile Ipv6 Addressing Using Transition Mechanisms
Global Mobile IPv6 Addressing using Transition Mechanisms Edgard Jamhour , Simone Storoz and Carlos Maziero Graduate Program in Applied Computer Science, Pontifical Catholic University of Paraná, Brazil. [email protected] [email protected] [email protected] Abstract and cellular networks) [2]. However, in order to provide connectivity to the global Internet, one must consider the The adoption of the Internet Protocol in mobile and shortage of IP version 4 (IPv4) addresses. The use of private wireless technologies has considerably increased the IPv4 addresses [4] was considered a temporary solution to number of hosts that can potentially access the global the IPv4 address shortage problem until a new addressing Internet. IPv6 is considered the long term solution for the scheme, IPv6, would be adopted [5]. Private addresses are IPv4 address shortage problem, but the transition from not considered a final solution because they are not IPv4 to IPv6 is supposed to be very gradual. Therefore, uniquely addressable. That is, a host with a private IPv4 there will be a long time during which both protocol address can start a session with a host with a public address, versions will coexist. To facilitate transition, the IETF using an address translation mechanism such as Network has set up a work group called NGTRANS (Next Address Translation (NAT), but not the contrary [6]. Generation TRANSition) which specifies mechanisms for supporting interoperability between IPv4 and IPv6. This IPv6 solves this problem by offering a virtually unlimited paper describes a new approach for implementing mobile address space. However, there is expected to be a long networks with global Internet connectivity using transition period during which it will be necessary for IPv4 transition mechanisms.

“Survey on Ipv4 and Ipv6 Using Dual Stack, Tunneling and Translation”
ISSN (Online) 2278-1021 IJARCCE ISSN (Print) 2319-5940 International Journal of Advanced Research in Computer and Communication Engineering ISO 3297:2007 Certified Vol. 7, Issue 2, February 2018 “Survey on IPv4 and IPv6 Using Dual Stack, Tunneling and Translation” Dr.Jitendranath Mungara1, Prof Shobha M S2, Satish Raj3, T Sudarshan Rao4, Yashish Thacker5, Saurabh Sunny6 HOD, Information Science & Engineering Department, NHCE, Bangalore, India1 Senior Professor, Information Science & Engineering Department, NHCE, Bangalore, India2 Student, B.Tech, Information Science & Engineering Department, NHCE, Bangalore, India3-6 Abstract: The introduction of IPv6 has opened up several questions with reference to its adaption and transition from IPv4 to IPv6 and is one of the crucial issues being frequently discussed in networking community today. IPv6 provides many seamless features that makes it far better protocol as compared to its predecessor IPv4. It is a well-known fact that IPv4 is a standard at present and is currently been deployed in almost all the Internet architecture, hence the transition process from IPv4 to IPv6 is very challenging. In order to avoid the transition, or in actual sense to delay it, many techniques have been introduced such as Dual stack, Tunneling and NAT. The objectives of this survey paper are twofold. Firstly, to highlight the issues related with the transition from IPv4 to IPv6. Secondly, to find the transition mechanism that can be provided seamlessly to end users where they will be able to use all the services of IPv4.The purpose is to tackle the issues and challenges that are likely to be faced during the transition from IPv4 to IPv6.
