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):

  區區四十里的溪流,就被攔截六十二次,如果遇到枯水之時,他們還要關閉閘門蓄水,春耕之時,下游鄉民急需河水灌養禾苗,這時候恰恰是河水枯竭之時,那些貴人們不理睬百姓的懇求,不但不放水,反而關閘蓄水,僅僅屬于南宮公主家的水磨就有四十七座之多。 亚洲在线成人色色   天底下,總有幾個人不那麼願意成為別人臣子的人。霍去病他們或許是,或許承認,雲瑯對大漢國卻總是親近不起來,他寧願用陰暗的心思來猜度皇帝,也不願意用自己的真心去觸踫這個世界。亚洲色图欧美色图   眼看著霍去病就要獲勝了,雁門邊軍就再也忍不住,這個勝利對他們來說太重要。   四個帶著兜帽的婦人掀開兜帽,露出滿是刺青的臉,冷冰冰的看著雲瑯,只要他一句話說不合適,她們就會一擁而上。亚洲情色网   史書上東方朔此人滑稽古怪,可是雲瑯見到的是那個還沒有被皇帝打擊的千瘡百孔並且自暴自棄的東方朔。

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.
