    Comparing IPv4 and IPv6 Performance

    The active measurements the RIPE NCC carried out on World IPv6 Day on 8 June 2011 included ICMP (Internet Control Message Protocol) and ICMP6 (ICMP for IPv6) measurements from our vantage points to selected hostnames of World IPv6 Day participants and other dual-stacked parties. We used these measurements to determine the performance of IPv4 versus IPv6 connections.

    The figure below shows a histogram of all relative IPv4 versus IPv6 performance data points collected during World IPv6 Day. A single data point consists of the ratio of IPv4 and IPv6 performance from a single vantage point to a single destination during a 10-minute interval.

    The image shows that while this distribution has a bell shape, it is a little "fatter" on the IPv4 side. This means that IPv4 is faster more often than IPv6. What this tells us is that you are slightly better off in an IPv4-only environment than in an IPv6-only environment. On a dual-stack client that unconditionally prefers IPv6 to IPv4, IPv4 is more often the faster protocol, but this is far from a universal truth. There is also a significant chance that IPv6 is faster, since the "IPv6-is-faster" part of the histogram also has a significant volume.

    Note that we measured ICMP and ICMP6, and not HTTP performance. Also, the IPv4 and IPv6 end points for a given hostname may be topologically and/or geographically in (very) different places, especially when proxies are used for IPv6 to IPv4 translation. In cases where the IPv4 and IPv6 destination end points are not at the same location, the distance between a vantage point and either the IPv4 or IPv6 destination end point has a large influence on the measured performance.

    In conclusion, we can say that comparable IPv4 and IPv6 performance can be seen as an indication of a mature deployment of both IPv4 and IPv6 in a network. In the data we analysed, we see that IPv4 is still generally faster then IPv6, but for a significant fraction of measurements IPv6 is the faster protocol.

    This is a moot point until anyone starts accepting IPv6 mail traffic which will likely take many years.

    Australia

    * AARNet recently completed a new network, AARNet 3. It is a high-speed network connecting academic and research customers in the major metropolitan centres, with international links to major ISPs in the US, Asia, and Europe. One of the design goals was to support both IPv4 and IPv6 protocols equally. It also supports multicast routing and jumbo frames.[11]
    * IPv6 Now Pty Ltd introduced the first[12] commercial-grade IPv6 tunnel broker service in Australia on April 30, 2008. Also, in June 2008, IPv6Now introduced the first dual stacked (IPv4 & IPv6) web hosting service.[13]
    * Internode is the first commercial ISP in Australia to have full IPv6 connectivity, and are currently making IPv6 available to customers.[14] The availability to customers was officially announced to Whirlpool on July 18, 2008.[15]
    * The Victorian State Government has granted $A350,000 to establish an IPv6 testbed network (VIC6) freely available to industry to evaluate their IPv6 products and strategies.[16]

    [edit] Belgium and the Netherlands

    * On July 13. 2010, native IPv6 over UMTS/GPRS was successfully tested in Belgium and The Netherlands within a vehicle platform as an Intelligent transportation system solution. The test was performed both in gsm and in tethering mode using a Nokia smart-phone. This test was performed by Logica Netherlands with in the SPITS project, in cooperation with Mobistar Belgium.[17]

    [edit] Canada

    * Fibrenoire, a Canadian Metro Ethernet fiber network operating in Quebec and Ontario, has been providing native IPv6 connectivity since 2009.
    * TekSavvy is currently deploying their own IPv6 network to customers as a Beta.

    [edit] China

    The China Next Generation Internet (CNGI, 中国下一代互联网) project is a five-year plan initiated by the Chinese government with the purpose of gaining a significant position in the development of the Internet through the early adoption of IPv6. Also, the CERNET (China Education and Research NETwork, 中国教育和科研计算机网, 教育网) has set up native IPv6 (CERNET2), and since then many academic institutions in China have joined CERNET2 for IPv6 connectivity.
    [edit] 2008 Olympic Games IPv6 showcase

    China showcased CNGI's IPv6 infrastructure at the 2008 Summer Olympic Games in Beijing.[18] The Olympics website was published on the IPv6 Internet at http://ipv6.beijing2008.cn/en (IP addresses: 2001:252:0:1::2008:6 and 2001:252:0:1::2008:8). All network operations of the Games were conducted using IPv6. This event was reported to be the largest showcase of IPv6 technology since the inception of IPv6.[19] The deployment of IPv6 was widespread in all related applications, from data networking and camera transmissions for sporting events, to civil applications, such as security cameras and taxis. The events were streamed live over the Internet and networked cars were able to monitor traffic conditions readily.
    [edit] CERNET-2

    CERNET-2 is probably the widest deployment of IPv6 in China. It is managed and operated jointly by 25 universities.[20] Students in Shanghai Jiao Tong University and Beijing University of Posts and Telecommunications, for example, get native IPv6.[21][22]
    [edit] Germany

    * M-Net, a regional carrier and ISP, offers an IPv6 PoP and native IPv6 (currently beta, add @v6.mnet-online.de to your username) for their customers.

    * Nerim, a small ISP, provides native IPv6 for all its clients since March 2003.[29]
    * Orange has done IPv6 experimentation, official support is still unclear.
    * OVH has implemented IPv6.[30]
    * FDN, a small associative ISP, has been providing native IPv6 since November 2008.[31]

    [edit] Hungary

    In Hungary Externet was the first ISP starting deploying IPv6 on its network in 2008 August.[32] The service was commercially available since 2009 May.[33][34]

    Magyar Telekom was running tests on its production environments since the beginning of 2009. Free customer trials started on November 2, 2009 for those on ADSL or Fiber Optic[35][36] Customers are given a /128 via DHCP-ND unless they register their DUID in which case they receive a /56 - using a static configuration results in a single /64.

    According to information on its homepage[37][38], UPC Hungary will start deploying IPv6 in 2011, finishing it in 2012.

    So far no other Hungarian ISP offers IPv6 connectivity.
    [edit] India

    * Department of Telecommunications, of Government of India is running a program for adoption of IPv6 in the Government network.
    * TEC (Telecommunication Engineering Center) is writing specification for IPv6 certification.
    * Sify Technologies Limited,[39] a private Internet service provider, rolled out IPv6 in 2005.[40] Sify has a dual-stack network that supports commercial services on IPv6 transport for its enterprise customers.[40] Sify is a sponsored member of 6Choice, a project by India-Europe cooperation to promote IPv6 adoption.[41] Sify is the first to launch a dual-stack commercial portal http://sify.com,.[42] Users were notified about the version of IP they use when they are accessing the front-page.
    * BSNL Broadband is reported to support IPv6 as of 2011. However there is no formal announcement from BSNL with regard to this.

    [edit] Luxembourg

    * RESTENA, the national research and education network, has been running IPv6 for a number of years. It is connected to the European GEANT2 network. In addition, it runs one of the country Internet exchanges, which supports IPv6 peering.[44] RESTENA also runs the .lu top level domain, which also supports IPv6.[45]
    * P&T Luxembourg, main telecom and Internet service providers, has announced they have production quality IPv6 connectivity since January 2009, with the first professional customers being connected as of September 2009.[46] Deployment of IPv6 to residential customers is expected to take place in 2010.[47]

    [edit] Netherlands

    * SURFnet, maintainer of the Dutch academical network SURFnet, introduced IPv6 to its network 1997, in the beginning using IPv6-to-IPv4 tunnels. Currently its backbone is entirely running dual-stack, supporting both native IPv4 and IPv6 to most of its users.[48]
    * XS4All is a major Dutch ISP. In 2002 XS4All was the first Dutch broadband provider to introduce IPv6 to its network,[49] but it has only been experimental. In May 2009 the provider provided the first native IPv6 DSL connections.[50] As of August 2010 native IPv6 DSL connections became available to almost all their customers.[51]
    * Business-orientated Internet provider BIT BV has been providing IPv6 to all their customers (DSL, FTTH, colocated) since 2004.[52]
    * SixXS has two private Dutch founders and has been partnering with IPv6 Internet service providers in many countries to provide IPv6 connectivity via IP tunnels to users worldwide since 2000. It started out as IPng.nl with a predominantly Dutch user base and reorganized as SixXS to be able to reach users internationally and be diversified in ISP support.[53] SixXS also provides various other related services and software which contributed significantly to IPv6 adoption and operation globally.
    * Business ISP Introweb provides an IPv6-only 8 Mbit/s ADSL connection for 6 euro per month to 100 customers as a pilot, both for companies to learn how to adapt to IPv6 as for themselves in working on a fully IPv6 enabled network.[54][55]
    * Signet is the first ISP in the country which provides IPv6 connectivity together with IPv4 on multiple national fiber networks (Eurofiber, Glasvezel Eindhoven, BRE, Glasnet Veghel, Ziggo, and Fiber Port).[56]
    * Most Dutch hosting companies, including the biggest one, Leaseweb, support IPv6, but customers by default get only IPv4 address.
    * Several government sites (such as Rijksoverheid.nl) are available via IPv6.[57]
    * On July 13. 2010, native IPv6 over UMTS/GPRS was successfully tested in Belgium and The Netherlands within a vehicle platform as an Intelligent transportation system solution. The test was performed both in gsm and in tethering mode using a Nokia smart-phone. This test was performed by Logica Netherlands with in the SPITS project,[58] in cooperation with Mobistar Belgium.[17]

    [edit] Philippines

    The government is in process of upgrading its facilities. Globe Telecom has already set in motion the transition of its core IP network to IPv6, noting that it is now fully prepared even as the Internet runs out of IPv4 addresses. Globe claims it is the first local telecommunication company to test IPv6 with Department of Science and Technology (Philippines). In some cases, like test networks or users, IPv6 or both maybe present.
    [edit] Poland

    * The Polish national research and education network began a IPv6 trial period in 2002.[59] As for now native IPv6 connectivity is available to numerous educational and private clients connected via citywide networks operated by local universities.
    * Polish Internet Exchange, a commercial and carrier-neutral Internet traffic exchange point, has facilitated IPv6 peering between numerous[60] operators since 2008.[61]

    [edit] Sweden

    [edit] United States

    * Comcast, a cable Internet provider, has started IPv6 trials.[69]
    * As with IPv4, the Department of Defense holds a larger IPv6 allocation than any other entity, a /13 block, enough to create almost 9 trillion (9×1012) local area networks, and 64 times as many as the next largest entity.[70]
    * Hurricane Electric (AS6939),[71] a Fremont, California Internet backbone and colocation provider, was an early IPv6 adopter and maintains a native IPv6 backbone and is today[update] one of the largest IPv6 connectivity and hosting providers in the United States. It was the first IPv6 backbone operator in the world to reach 200 IPv6 BGP adjacencies. Through its IPv6 tunnel broker service,[72] Hurricane also provides free IPv6 connectivity to users in the United States and in several other countries.
    * Sonic.net, a Santa Rosa, California-based Internet provider, offers partial support for IPv6. They assign a /60 to any customer requesting address space and deliver the IPv6 packets over a 6in4 tunnel. The RDNS authoritative servers for the assigned IPv6 space do answer IPv6 requests, but the recursive DNS servers provided for customer use are IPv4-only.
    * AT&T started testing their networks with IPv6 back in 2006.[73] AT&T also participated in World IPv6 Day.

    You completely missed my point.

    Everybody is building IPv6 networks and will use them for million other things, but it does not mean anyone would start accepting email over IPv6 until they figure out how to filter it.

    Because IPv6 completely breaks the currently dominant methodologies of filtering by IP reputation (you can send a billion emails each from its own IP) the easiest way out for any postmaster is to keep all mail on IPv4.

    If I missed any reason why anyone would want to allow mail delivery via IPv6, please let me know.

    I think the speed of IPv6 transactions will improve when the hardware being used is specifically optimized for IPv6, and that won't happen until the major push toward it. It's a lot like HDTV in the USA...at first it was available only a few places, but after a decade it's becoming the standard.
