IPv4 depletion: what really happens and how REG.RU deals with it



    At the end of September 2013, REG.RU updated the VPS hosting tariff line, allowing its customers to connect an unlimited number of additional IPv4s, which might look somewhat unexpectedly due to the lack of IP addresses, which has been widely reported in the international press and blogosphere for several years.

    On Habr, the IPv4 crisis has been discussed for a long time - Habra residents have been actively writing articles on this topic since 2007, naming the most diverse dates for the complete depletion of IP-address supplies. Users were waiting for this event in early 2011 , then on August 20, 2012 , and even tried to independently calculate when IPv4 addresses would end. However, not one of the forecasts has been justified yet.

    In addition, you can find a large number of analytical and review articles on the situation on the IP-address market. Some of them tell about the history of the problem , others about the pros and cons of the transition from IPv4 to IPv6 or about the current offers on the Russian market. We will try to combine all these topics, presenting the most complete picture of what is happening.

    A few words about IP allocation mechanics

    IPv4 allows you to use 4.23 billion addresses, which are distributed by the American organization IANA. This process is as follows: IANA delegates its authority to assign IP addresses to regional registrars (RIRs) in the form of Class A ranges (/ 8). Regional registrars, in turn, delegate smaller ranges to Internet providers.

    Currently there are 5 RIRs:
    - American Registry for Internet Numbers (ARIN) - for North America;
    - RIPE Network Coordination Center (RIPE NCC) - for Europe, the Middle East and Central Asia;
    - Asia-Pacific Network Information Center (APNIC) - for Asia and the Pacific;
    - Latin American and Caribbean Internet Addresses Registry (LACNIC) - for Latin America and the Caribbean;
    - African Network Information Center (AfriNIC) - for Africa.

    A bit of history

    Experts began talking about the upcoming shortage of IPv4 addresses back in the 80s of the last century, when the number of Internet sites on the Web began to grow rapidly. In the 90s, to solve this problem, the Internet Engineering Council (IETF) developed a number of new technologies, including Classless Addressing (CIDR), NAT, and the new version of IP - IPv6.

    Exhaustion Timeline

    - In February 2011, IANA allocated the last five remaining blocks / 8 from its address space to regional Internet registrars;
    - April 15, 2011 APNIC, the first of the regional registrars, stopped the free issuance of IP addresses;
    - September 14, 2012 there was a depletion of IPv4 reserves of the regional registrar RIPE NCC;
    - On August 1, 2013, the ARIN registrar announced that only 2 IPv4 blocks, size / 8, remained at its disposal.

    IPv6 vs IPv4

    IPv6 was created to solve the problems that IPv4 cannot handle. First of all, this should happen by using the address length of 128 bits instead of 32.

    After the IPv4 address space is over, the sixth and fourth generation protocols will be used in parallel, with a gradual increase in the proportion of IPv6 traffic compared to IPv4. This situation will become possible due to the presence of a large number of "obsolete" devices that do not support IPv6 and require special conversion to work with devices that use only IPv6.

    June 8, 2011 saw IPv6 International Day, an event to test the readiness of the global Internet community for the transition from IPv4 to IPv6, in which participating companies added IPv6 recordings to their sites for one day. REG.RU, along with Google, Yahoo !, Yandex and many other companies, also participated in testing.

    A year later, on June 6, 2012, IPv6 was launched worldwide. However, the new protocol has not yet received wide distribution. For example, in Russia, statistics on the transition to IPv6 now looks like this (data for October 2013):

    In the .RU zone,
    IPv4 addresses alone have more than 3.4 million domains (91.84%);
    IPv4 and IPv6 addresses have more than 305 thousand domains (8.16);
    Only IPv6 addresses have 108 domains (0.00%).

    In the zone .РФ
    Only IPv4 addresses have more than 430 thousand domains (92.74%);
    IPv4 and IPv6 addresses have more than 34 thousand domains (7.26);
    Only IPv6 addresses have 2 domains (0.00%).

    REG.RU on the IPv4 market

    Despite the fact that now IPv4 reserves are running out, REG.RU is able to provide IPv4 addresses in virtually unlimited quantities. At the same time, prices are among the lowest in the market - from 18 rubles per month for 1 additional IP. You can rent IP addresses in blocks together with any VPS or Dedicated tariff.
