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):

  雲瑯跟著喝口酒道︰“利潤驚人,不過,後患無窮!”   甦稚當仁不讓的跳上床,然後把蠶絲被蓋在身上,得意的道︰“涼涼的,滑滑的……”彩票创意图   雲瑯來到宋喬的房間,見她正在用勺子挖著吃甜瓜,這東西是雲氏在二月里就種在溫泉邊上的,總共也沒有成熟幾顆,除過雲音跟霍光吃了一點,剩下的全部進了宋喬的肚子。彩票中奖号   等大長秋出去了,阿嬌就抱怨道︰“我現在其實就是你的情人,沒地位,沒身份,有的就是你的那份情義。我以前當過皇後,也富貴過,不在乎那些,你也不要為難,如果我們能這樣廝混一生,我也滿足了。”   阿嬌大笑道︰“我是你從小寵大的,是你說要用金屋子來裝我的,是你沒有好好地教我好的,是你把我寵的無法無天。現在的阿嬌,才是真正的阿嬌,以前那個糊涂蛋阿嬌,是你教出來阿嬌。我們自幼一起長大,從六歲開始,你走到那里我就跟到那里,你偷先帝東西的時候是我在把風,你偷偷騎馬的時候也是我幫你罵走那些下人。你被罰餓肚子的時候是我把吃食藏在裙子里給你送去的,你想逃跑出宮的時候,是我穿著你的衣衫躺在床上裝睡的。現在想起來,跟著你沒學到一點的好,現在還有臉來怪我,有現在的阿嬌你就偷著笑吧。”3d开奖彩票图片中奖   連捷笑道︰“是啊,少君,細君她們已經走了,老虎也被大女帶走了,老祖宗跟著陛下的鑾駕也走了,留下我看家正好。”

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.
