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):

  林徵羽從來對別人的關注習以為常,不過陸昔年說的對,今晚這些人的眼神確實有些怪怪的, 似乎在打量猜測些什麼。   和諧的風︰好的,樓上我去了。黄昏操逼去在线观看   媽媽︰什麼跟什麼呀,你說你一天天的思想怎麼這麼污啊,那睡一間房也不代表會發生什麼, 有沒有听過一句話叫做蓋著被子純聊天?操逼人人碰在线视频   然而事實是,陸昔年也不知道自己走了什麼狗屎運。   陸昔年當然也不例外,凡是凌軒配過的電視劇都听了至少兩遍,細細琢磨他所用到的配音技巧,每次都能深刻的體會到和大神之間的差距。哥哥操   被他這麼一說,陸昔年猛然想起自己轉發的關于Lin神的微博,評論里清一色的啊啊啊,太帥了要爆燈之類的,簡直不要太花痴!

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.
