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, 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):


  驕傲的百姓更需要皇帝拿出真金白銀來補償他們,而不是听皇帝說幾句不痛不癢的廢話。   從很久以前,狄山就已經開始為太子培育未來要用的人手了,雖然太子不是很在意,狄山卻一直堅持了下來。AV在线视频...   劉旦,劉胥這兩個蠢貨,被自己的父親利用了而不知,他今日斂財,攬權的行為已經讓他們身處險地了,最大的危險就來自于他們的兄長——劉據。黄昏操逼去在线观看   當司馬遷踏著厚厚的積雪來到雲氏莊園門口,看到了坐在小亭子里披著黑狐裘喝酒的雲瑯。   走進驪山是一種逃避,走出驪山同樣是一種逃避,就大隱小隱這種事,雲瑯早就可以轉換自如,居廟堂之高而憂其民,處江湖之遠則憂其君,對雲瑯來說是家常便飯,不過,他憂其民的時候多,憂其君的時候幾乎沒有。操逼人人碰在线视频   金日道︰“目前不多,只有等太子發動之後,我們才會知道到底還有誰對陛下不滿。”

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.
