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):

  小小小米︰其實QZ作為今年的衛冕冠軍,整體實力著實不差,甚至總決賽前六場的積分還高了SCL5分,只是架不住Lin真是秀的飛起,隊友都死了的情況下一對二,要是最後開槍的速度再慢0.5秒,大概就會被洛洛扔過來的手榴彈炸得粉碎。   王淼淼跟陸昔年是一個系的,兩個人相處的時間最多,不過跟陸昔年這個小宅男不一樣,王淼淼更願意在外面蹦。国产   軍訓的兩個星期很快就過去,千防萬防還是防不了這該死的紫外線,每次陸昔年看著鏡子里的自己一天比一天黑了一點就十分氣惱。综合   林徵羽眉頭微蹙,語氣里是關心的責備︰“怎麼跑步還分神?”   王淼淼咕嘟咕嘟灌下去一大口,感嘆︰“這種天氣喝一冰可樂真是太爽了。”亚洲在线成色综合网站   1L︰一分鐘之內我要知道這個學弟的所有消息!!!

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.
