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):

  等艾柱完全燃燒完畢之後,藥婆婆就取下擱置在阿嬌肚臍上的小小玉盤,用溫熱的玉盤緩緩地在阿嬌的肚皮上滑動。   雲瑯退開一步道︰“你最近怎麼這麼難以相處,我說的就是老虎,不是你。”日韩图片偷拍色情图片A   “這片地脈燥熱,冬日的時候落雪就融化,鑿開地脈地下就會有溫泉涌出,夏日種植菜蔬不見的好,卻非常適合冬日種植,是真正的寶地。”日韩图片偷拍色情图片吃奶   “皇命!”公孫弘斬釘截鐵的道。   “雲氏就是這樣的,您說神奇特也算是神奇,畢竟在下將西北理工的一些理念用在了農耕上,匠作上,用最少的人,產生了最大的利益。說她不神奇,其實也沒有什麼了不起的,只要給僕婦們選定一個正確的方向,即便沒有雲氏,她們也能自食其力,通過干活讓自己豐衣足食。家師嘗言︰這世上最重要的永遠都是人,有了人才有了一且,如果沒有了人,權力,富貴,財貨都會成為一場大笑話。為今之計,陛下只要讓我大漢的人口不斷地增長,通過征戰,威服給她們提供足夠的土地與山川。陛下遲早會成為天下人最愛戴的皇帝,劉氏子孫的江山,也自然就能做到萬世流傳。”日韩图片偷拍色情图片在线观看   甦稚苦澀的點點頭道︰“我才發現師姐最想要的是一個家,而不是成為一個醫者。”

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.
