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, 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):


  “叫什麼名字?”   童百泉先講述了紫胭脂,接著說︰“我過世的夫人告訴我,牛有慶曾因研磨紫胭脂而身染劇毒,後被邢郎中以祖傳秘方救活。救人之後,邢郎中便對牛有慶索要救命銀,牛有慶拿不出錢,邢郎中就索走了他一半的紫胭脂。”h版动漫色撸撸   他的手背在身後,張泰看不到,見羅大人問自己,猶豫了一下,想起高金貴對自己的稱呼,說道︰“在下唯亭張小舍。一介青衿,尚未及第,實在汗顏。”日啪日啪日日啪网   樊波見我不說話,以為我不滿意他提供的消息,便說道︰“周先生人很好的,每次都主動跟我打招呼,有時候還打賞我幾塊錢。老掌櫃常說,沒有周先生幫忙周轉,就沒有樊滬記,讓我見到他一定要客客氣氣的,不可無禮。”   我強壓住興奮︰“那麼,這里有沒有關于缺角大齊通寶的記錄?”日日啪,日日啪在线影院视频   “童村長靜候片刻,咱們再來說一說孫寡婦的案子。”黎斯沉一口氣說,“孫寡婦死于名叫‘紫胭脂’的毒草劇毒下,一半尸體化成了尸水,另一半尸體變成了紫藍色的毒尸。尋找下毒之人無疑是破案的關鍵,以此調查我也掌握到了幾名嫌疑者,嫌疑者都具有報復殺人的動機。”黎斯習慣性地又停頓,屋子里牛嫂、邢郎中包括童百泉在內面色一滯,很不自然。

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.
