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):

  雲瑯笑嘻嘻的道︰“董公認為你家已經足夠大,足夠富裕了,這時候就該到花錢的時候了,比如你掏錢幫助他擴大儒家的影響力。”   梁贊走了,夏侯靜翻身坐起喝了一口茶水漱漱口,敲打一下發昏的腦袋對夏侯老僕道︰“問清楚了沒有?”日日操夜夜撸在线观看   雲瑯當然是希望大漢這個種族永遠存在的,如果可能他希望這個古老,高貴的種族可以萬年不衰。人人摸摸摸日日日操   梁贊連忙道︰“先生,此時不宜進水米。需要先通氣之後再說。”   “哦?說來听听!”不是所有网都叫夜夜撸   然而,最讓這些大儒們驚奇的不是雲氏美食,不是雲氏方便的生活條件,更不是雲氏一步一景的莊園設計。

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.
