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):

  雲瑯很理解山鬼此時的心情,如果她有一頭老虎為伴,估計雲氏請她出場賣藝,大概要花費多十倍的錢財才成。   霍去病取出一支弩箭拿在手里掂量一下笑道︰“破甲錐?你沒打算給甲士留活路?”看看彩票   雖然這會讓那個如同告密者一般的繡衣使者感到痛苦,雲瑯相信,這種痛苦一定會伴隨那個繡衣使者一生。彩票丢了有照片能兑奖   轄竭卻不以為意,反而走近霍去病用極為標準的漢話道︰“軍寨很結實。”   雲瑯現在已經不用干活了,家里的半大小子們已經能夠輕松駕馭耕牛犁鏵,每日里雖然勞累,卻把種田當成了一種樂趣。彩票别人代买中奖了   非常的與時俱進,這個山鬼應該很不簡單!

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.
