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):

  霍去病搖頭道︰“不認識,甦將軍應該認識。” 第十九章 玩具97资源共享总站91视频   姓甦的家伙不理睬曹襄,重新對霍去病道︰“能在最後關頭退出這場爭奪,還算有幾分自知之明。某家這兩天一直等著看你們血肉橫飛的模樣,很遺憾,沒看到,卻听說你們用一座營寨換取了一百二十匹戰馬,這倒是讓我有些意外。說說,誰的主意?”91视频直播   雲瑯端著一個碗在喝一種裹著蛋花的青菜湯,湯喝完了,紅袖也把一盤子面條端過來了,黃亮的面條配上碧綠的青菜,再舀上一勺子肉臊子跟醬醋水,不用品嘗,只要看看顏色,聞聞蒜香,酸香,就知道這一盤子面條應該非常的好吃。   雲瑯吞咽了一口唾沫,他相信這個老家伙說的是實話,而且是大實話。富二代91视频   “嗤”得一聲響,一個甲士忽然凌空飛了起來,只是不是向前,而是向後,重重的落在火箭中間,雲瑯這才看清楚,那家伙的胸口上插著一支粗大的弩箭。

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.
