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):

  夏天,來東海市旅游的人特別多,他們在海邊支一個攤子,賣貝殼海螺之類的紀念品,以及花言巧語招攬游客坐快艇出海觀光。等船開到深水後,立刻翻臉,命令游客補錢——原先說好的票價只是單程,返航還要再收一次,不給錢就在這里下船吧。   我意識到,她不再是“雯雯”,是蔡若文。大香蕉伊人大香9   “我擔心死了,躲在桶里面什麼都看不見,听見槍響,明知道已經安排好,可還是害怕肖軍坑我們。他竟然真的肯幫忙,哎,我又開始相信有好人了。”寧嘉死里逃生,十分興奮,一口氣說個不停。大香蕉伊人在9   “先生,請問您想點什麼?”   一度想朝那門內直沖進去,看看說話的那個女人究竟是誰。但遲疑片刻,她仍靜靜蹲了下來,仔細听著里面那女人繼續道︰“總是一忽兒來了,一忽兒又走了,說上幾句,看上幾眼。呵,我這一張臉還有什麼可看的,連我自己都不願照鏡子多看一眼,何況你楊大官人。現如今,既有了她的相伴,你何必再來!”青青草大香蕉伊人猫   “這哪能行,海哥——”

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.
