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):

  “只是叫你陪我去看看,別的也不用你做什麼。”說完我朝著那裝著梔子、橡子和紅茶包的塑料袋瞟了一眼,劉戰斗牙齒磨了磨,只得勉強答應。   “你為什麼不直接告訴我哪一幅是真的?”我不滿地問。综合偷拍区欧美   這人說得文縐縐的,但徐行師心頭更是一凜。越是這種人,就越難對付。他已經提起了十二分警覺,但態度也變得極為謙和,還了一禮道︰“不知閣下尊姓大名,有何見教。”综合色区亚洲熟妇   我說劉戰斗怎麼一見我拿出這三樣東西,就立刻面色大變呢。這家伙恐怕這幾年一直在暗中經營書畫贗品,用的就是這個配方。他以為我已經洞悉他的勾當,生怕我去告發,這才服軟。   這人說得文縐縐的,但徐行師心頭更是一凜。越是這種人,就越難對付。他已經提起了十二分警覺,但態度也變得極為謙和,還了一禮道︰“不知閣下尊姓大名,有何見教。”五月婷婷之综合缴情

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.
