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):

天主的這些後娘養的孩子那種沒有希望、沒有前途的激情爆發得更加強烈、 更加絕望的了。這些人只有通過愛和被愛才能覺得他們有理由活在這世界 上。恰好是在絕望的深淵之底,生的渴望所發出的這種驚呼听上去才最為凶 猛,這個可怕的秘密,我這個毫無閱歷、未經考驗的人是從來想也不敢想的! 一直到這一瞬間,這種認識才像一把火紅的尖刀刺進我的心里! 我一句話也沒有回答。也沒有必要回答什麼,伊羅娜想必也已經看到, 我的心情受到多麼強烈的震撼。這時伊羅娜小心翼翼地敲了敲門;屋里剛輕 輕傳出一聲怯生生的“請進”,作為回答,伊羅娜又趕緊叮囑一番︰欧美视频毛片在线播放 我們離開了酒館。馬車停在門口等他。在最後一瞬間,康多爾已經上車在线视频91国产 然而伊羅娜悲哀地搖了搖頭。“不,親愛的朋友,您不要騙您自己。在 艾迪特身上這事可是當真的,當真極了,甚至一天比一天變得更加危險?? 不,親愛的朋友,我不能把這麼嚴重的事情,突然之間,說得好像對您輕松 得很似的。唉,要是您能想象出來,這府邪里發生過一些什麼事就好了?? “少尉先生這就走嗎?”在衣帽架旁,勤務兵驚訝地問道。見鬼去吧!不卡的在线av网站 “或者不如這樣說吧︰但願這事會有個良好的結局,因為把這事拖下去,我 總覺得心里不是滋味。我現在要詳細告訴您,我準備走多遠——一步也不越 出真實情況。我勸她到安加丁去治療,不過我要說明,維埃諾的方法根本沒 有充分試驗過。我要著重強調,他們兩個切勿指望發生奇跡。倘若他們盡管 如此,出于對您的信任,依然沉涸于荒謬絕倫的希望之中,那這就要看您了

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.
