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):

  雲哲連忙道︰“兒臣擔心父皇的身體,這才兩個月的時間,您的鬢間白發多了一倍。”   這些名頭都是因為社會大分工中一一產生的,所以說啊,我們活在一個很大的團體中。彩票中奖截图   空氣中飄來一股子可疑的味道,老虎大王顧不得找雲瑯的麻煩,凶狠的向味道飄來的方向奔跑過去。福利彩票店图片实拍   雲瑯松了一口氣,只是天空總是陰沉沉的,讓人爽利不起來。   雲瑯停下手里的活計,若有所思的道︰“匈奴人只是燒殺搶掠,對那一片土地只會帶來傷害,沒有半點好處。我們就不一樣了,我們帶去的傷害只是暫時的,為了增加農作物產量,我們帶去了先進的農作技術跟工具,為了供應我們精美的器物,我們也帶去了先進的工藝……更不要說我們還在那里逼迫胡人說漢話,行漢禮……如此幾十上百年之後啊,他們就能從野人過渡到文明國家。你必須要懂得一點,只有毀滅跟傷痛才能真正的催人上進,逼迫他們做出改變。否則,他們的種族遲早會消失在歷史長河里。”彩票店布置   所以,雲瑯決定經商的甜頭必須給人家,嘗到了經商的甜味,他們才能堅定不移的將經商之路走下去。

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.
