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):

  這下劉莽冷靜下來了,我勒個去,如果剛才繼續留在場上……得被麥迪虐得懷疑人生吧!   第二天,休息日,6號有比賽,是打魔術隊,不好打,盡管魔術隊的當家球星格蘭特?希爾又一次賽季還沒開始就報銷了,但他們還有新晉的第一分衛候選人特雷西?麥克格雷迪。咪咪色网 亚洲se网   江心遠瞧著還想留下陪陪黎舟,但是黎舟卻不想和他多說什麼,只借口說自己累了想睡,江心遠又裝模作樣地看了一圈,這才離去。   一連幾天黎舟都如約跟在黎江身邊,陪他打籃球,又接送他去學小提琴,有些閑暇時候在家里閣樓上那個藏書室還一起看書。藏書室有一片偌大的玻璃窗,不規則的三角形,陽光很好,小的時候他和黎江經常來這里捉迷藏,在記憶里很大的房間,現在看來雖然也不小,但已不再是需要仰視的高度了。爱se网   “對,今天剛好踫到老板,他硬要給我這兩張,你擔心被撞倒可以和後排的球迷換位置,他們會很樂意。”劉莽隨口應道。

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.
