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):

  雲瑯搖頭道︰“我其實沒有潔癖,只是跟你們這群髒人比起來,顯得更加干淨一些罷了。你們髒,匈奴人比你們髒一百倍,知道疫病是怎麼來的麼?就是因為髒才會出疫病!現在是初秋,正是疫病爆發的時候,一個弄不好,死一軍營的人都不是難事。”   一個絕望的人,驀然間獲得了最大的權力,天知道會在部族中引起怎樣的波瀾。不是所有都叫日夜撸   曹襄不知道自己為什麼要說出這三個字,狠狠地在嘴巴上抽了一巴掌可憐兮兮的瞅著雲瑯他們三個。影音先锋资源网日夜撸   如果在這里屯駐一支大軍,偌大的河套就完全被大漢抱在懷里了。   其中氐人苻堅更為大漢文明創造了投鞭斷流,風聲鶴唳等著名的故事。不是什么网都叫日夜撸   雲瑯抬頭看看白登山上依舊飄揚的謝長川帥旗道︰“謝長川依舊在戰斗,說明我們暫時是安全的。”

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.
