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):

  大漢百姓或許不欠這位君王什麼,雲瑯以為,後世子孫們之所以能一次次的在灰燼上重新建立漢人的國度,讓這個頑強的種族歷經數千載歷久而彌新的體魄中,絕對有他的靈魂在支撐。 色五月色五天色情网   所以,今年秋日,勛貴之家的子弟很少有通過秋日大考進入朝堂為官的。丁香五月综合缴情电影   雲瑯緩緩地將身體靠在錦榻上,瞅著房頂道︰“皇帝開了一個很壞的開頭,于是,天下間有野心的人就開始蠢蠢欲動了。皇帝開始不把自己當皇帝,當成了陰謀家,就不能怪別人對他用所有的手段。許莫負留給劉據的五道箴言,弄清楚了嗎?”   曹襄站起身伸了一個懶腰,還打了一個哈欠道︰“愛高興不高興,我累了,要睡覺。”丁香五月缴情在线   劉徹再一次出現在大殿上,雲哲立刻湊過去道︰“陛下,我父親說您這樣練武對您的身體有害無益。”

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.
