We are responsible for global coordination of the Internet Protocol addressing systems, as well as the Autonomous System Numbers used for routing Internet traffic.

Currently there are two types of Internet Protocol (IP) addresses in active use: IP version 4 (IPv4) and IP version 6 (IPv6). IPv4 was initially deployed on 1 January 1983 and is still the most commonly used version. IPv4 addresses are 32-bit numbers often expressed as 4 octets in “dotted decimal” notation (for example, 192.0.2.53). Deployment of the IPv6 protocol began in 1999. IPv6 addresses are 128-bit numbers and are conventionally expressed using hexadecimal strings (for example, 2001:0db8:582:ae33::29).

Both IPv4 and IPv6 addresses are generally assigned in a hierarchical manner. Users are assigned IP addresses by Internet service providers (ISPs). ISPs obtain allocations of IP addresses from a local Internet registry (LIR) or National Internet Registry (NIR), or from their appropriate Regional Internet Registry (RIR):

  別說,未來的波波維奇想到的這個防守方式,對于投射能力拙計的運動型外線來說,效果是真的不錯,弗朗西斯沒辦法了,又不敢在外面投,一般來說接球投三分節奏感是最好的,如果是運著球投三分,大部分人需要調整,這一調整,對方防守球員直接就撲上來了,這時候走又走不開,再運球就違例,傳球也不一定第一時間傳得出去,頂著防守強投又不是什麼好主意,畢竟不是誰都和麥迪一樣浪得飛起,也不是誰都有麥迪那樣浪的資本。 眠整整三日,第四日朝陽才露頭就被烏雲籠罩,而後春雨霏霏!美女自拍   至于下一場比賽比賽會打得怎麼樣?現在不是考慮這個的時候,正所謂人生得意須盡歡……好不容易有這麼個超級巨星的實力,不爽一波都對不起自己!自拍偷拍图片   看到劉莽第三罰居然空心命中!現場球迷又一次愣了,最後還是給了掌聲……   ……亚洲巨乳自拍在线视频   不過現在的話,劉莽有些著急了,這投籃基本等于沒有啊!

Our primary role for IP addresses is to allocate pools of unallocated addresses to the RIRs according to their needs as described by global policy and to document protocol assignments made by the IETF. When an RIR requires more IP addresses for allocation or assignment within its region, we make an additional allocation to the RIR. We do not make allocations directly to ISPs or end users except in specific circumstances, such as allocations of multicast addresses or other protocol specific needs.
