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):

  “這麼听話?我以為你會說草地已經夠軟了直接鋪睡袋就行。”林徵羽故意逗他。   這套漫畫三年前出版過一次, 也是唯一一次, 到目前為止有價無市,更何況是全新的套裝。日日操人在线视频   陸昔年洗完碗從廚房出來正好看到這個笑容,再看到林徵羽手里拿著的相冊時,臉一下就紅了。日日操操青青草   大半杯水盡數灑在機械鍵盤上,白色的鍵盤燈瞬間熄滅。見勢不妙,小糯米退了幾步趁機想逃。被林徵羽提起來,短短的四肢在空中反射性揮舞幾下,然後認命的縮了縮脖子,黑豆子般的眼里散發著無辜的光芒。   “回來了?”剛走近林徵羽就發現了他,“我這邊也差不多了,要不要一起去買漁具,櫃台那邊好像有賣。”日日操视频手机播放   這一刻陸昔年清楚的意識到, 這不是夢,也不是他幻想出來的產物。

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.
