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):

  對于這件事,雲瑯從來都回答的斬釘截鐵。   跟著張安世已經有一陣子了,金日發現,開銀行並不難,只要有錢,再從皇帝那里拿到準許文書,弄一座富麗堂皇的大樓,用賬房先生跟美女把大樓填滿,然後開業就好。日日啪,日日啪影院,日日啪在线影院   當紅袖跟霍光的意見統一之後,一件事也就基本被確定了。夜夜撸日日操天天舔   霍光沒有等到雲音,略微有些失望,眼見太陽就要落下,就嘆口氣,拍拍老虎,一步一挪的向姑臧城走去。   天色完全黑下來了,黑色的蝙蝠在院子里上下飛舞吞食昆蟲,宋喬的臉色陰沉的就像是鍋底,張安世跟金日羞愧的跪在宋喬面前無顏以對。日日啪夜夜啪在线看   只有雲瑯自己清楚,在河西這片新開闢的土地上,自己沒有任何可以借用的先例。

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.
