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):

  夜晚的受降城非常的安靜,只有身邊的這條大河在嗚嗚咽咽的流淌,因為月亮興起的波瀾拍在城牆上,讓雲瑯驚疑不定,遲遲不敢入睡。   何愁有怔怔的看著雲瑯搖搖頭道︰“還是不問了,直到現在你依然在對老夫撒謊……陳年舊事翻不得,翻一次就惡臭燻天,听一次就少活十年,還是忘了的好……”欧美   曹襄咳嗽一聲道︰“你忘了,我挺著一個大肚子的時候,比這要難受的太多了,那時候只想著什麼時候會死,現在卻只想著什麼時候能到地頭。這不,還不是被我給忍耐下來了,知道不,你夫君遭受了一路的折磨,卻一聲都不吭,哪怕是面對這個魔鬼,我也沒服軟……可惜啊,去病,阿瑯,阿敢他們都在受降城,否則,就這件事足夠我吹噓三五年的。”国产   他的到來讓受降城里的羌人,終于誠心誠意的接受了大漢的統治。   “不成啊,太疼了,給我一個東西咬……”综合   雲瑯看著燃燒猛烈的竹簡淡淡的道︰“听說他欲為淮南王相,應該繼續過著錦衣玉食的日子吧!”

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.
