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):

  馬夫摸摸嘴上的胡茬子嘿嘿笑道︰“想殺耶耶的人多了,最後死的都是他們!別耽擱,把文牒給我看一下,一會還要喂馬呢!”   干休所啊,多肥的生意啊!一本道色悠悠久久久亚洲   曹襄突然吃吃的笑了,仰著頭道︰“我的膽子太小了,這我知道。我更知道,如果我進了草原,去病哪怕將草原翻個底朝天也會找到我。如果我進了草原,阿敢寧願跑遍草原也會找到我。如果我進了草原,阿瑯的膽子雖然也不夠大,可是啊,他一定會毫不猶豫的鑽進草原深處,在我最需要他的時候出現在我的面前。既然如此,現在去病,阿敢去向不明,我有什麼理由不進入草原深處?”日韩图片偷拍色情图片AV   霍去病在吃到燻肉炒野蔥之後,就重新愛上了馬肉,至于曹襄跟李敢,他們一致認為應該把草原上的牛羊全部弄成燻肉帶回去。   雲瑯指著帳篷外邊的白登山道︰“這一次功勞可能不是很值錢,畢竟,要封賞的人太多了,我比較贊同去病的說法,多要些土地,安置我們那些受傷的兄弟。一個個在家里都是不受待見的主,分出來住在驪山,有我們兄弟幾個在,比住在大宅門里好的太多了。哼,驪山可是一個風水寶地,山上物產豐富,山下土地肥沃,旁邊就是渭水,坐船就能直奔關中各地,以後啊,這地方甚至會成為大漢國的經濟,文化中心。”日韩图片偷拍色情图片   雲瑯指著帳篷外邊的白登山道︰“這一次功勞可能不是很值錢,畢竟,要封賞的人太多了,我比較贊同去病的說法,多要些土地,安置我們那些受傷的兄弟。一個個在家里都是不受待見的主,分出來住在驪山,有我們兄弟幾個在,比住在大宅門里好的太多了。哼,驪山可是一個風水寶地,山上物產豐富,山下土地肥沃,旁邊就是渭水,坐船就能直奔關中各地,以後啊,這地方甚至會成為大漢國的經濟,文化中心。”

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.
