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):

  雲瑯抬頭看看散布在原野上的僕役們笑道︰“這世上美好的東西多了去了,你缺少一雙會發現的眼楮。”   這個過程很難捱過去,雲瑯不動如山,任憑甦稚撲在他身上,啃咬,撕扯……亚洲自拍   雲瑯笑眯眯的道︰“你還可以試試在別的東西上刻字,比如在膠泥上,趁著濕泥好雕刻的時候把字刻上去,然後放進爐火中煆燒,最後成印。或者是把字雕刻在鑄造好的鉛塊上,也能成印,至于具體的該怎麼做我是不懂的,就看你如何做了。”偷拍自拍图片   張湯皺眉道︰“你這是不願意給黃氏任何機會是吧?千萬不要忘記,自從太祖高皇帝在漢中為王的時候,黃氏就是從龍之臣,太祖屢次兵敗于項羽,黃氏從未動搖過,依舊一心一意的支持太祖出兵陳倉。可以說,太祖高皇帝最終之所以能夠定鼎天下,黃氏功不可沒,不論是阿嬌貴人,還是陛下都不可能名正言順的支持你掀翻黃氏,否則,會讓天下人覺得陛下薄涼。”   極為懶惰的曹襄到了開鐮的日子也不敢怠慢,也是一身麻衣,腰里還別著一把鐮刀,腳下踩著草鞋,看樣子是要大干一場的。自拍亚洲偷丁香五月   可以享受難得的一個清涼舒適的下午時光。

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.
