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):

  “這麼簡單?”   “什麼事?”曹襄不解的問道。日日啪 日日啪图片   雲家的兩個美艷的茶娘,已經在亭子里恭候,一個巧手烹茶,另一個有意無意的撥弄一下琴弦,似乎在一瞬間,琴聲就與淙淙的溪流,風吹柳葉的聲響融為一體。日日啪 日日啪在线影院图片   劉徹笑道︰“就是那個懂得祭祀灶神求福、種谷得金、長生不老,能驅鬼神,擅用藥物,能讓人返老還童,去過蓬萊仙島的李少君。阿嬌,你現在還敢賭嗎?”   只要小蟲去了長門宮被人攔住了,那就表示皇帝來到了長門宮。日夜撸影音先锋下载   “劉陵當然需要那首歌,那個該死的女人一到長安就讓人到處傳唱這首歌。曲子好听,韻調簡單,又朗朗上口,現在連水井邊挑水的婦人都會唱這首《美人歌》。雲瑯,我不是早就告訴你了,要離這個女人遠點嗎,你不但不听話,反而給她寫歌,不出事則罷,一旦出事,那就是滔天大禍。”

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.
