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):

  “這是什麼骨頭?”雲瑯用夢囈一般的語氣問道……有了這具骸骨,瓖嵌在石壁上的各色正在閃耀著光芒的寶石就黯然失色了。 我被农民工大jb插   兩人一虎沿著山路很快就下到了瀑布邊上,雲瑯輕松地攀上岩壁,找到了那塊石頭用力的一拉,山門立刻洞開。亚洲成人社区   每個人都有隱私,各安其便最好。   雲瑯松了一口氣,忍著怒火從床上跳下來,小心地把他的手合上,推著孟大的肩膀道︰“好了,現在你是它母親了,你們要好好相處,如果想找人說話,去那邊找曹襄!”偷拍久久国产视频   曹襄笑道︰“你如果不想讓陛下來驪山,就要想辦法讓阿嬌長命百歲,所以啊,我去長門宮的另一邊蓋莊子去。”

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.
