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):

  好不容易出了迷宮,看到了那座白色的白玉丹樨,雲瑯的心才算是平靜了下來。   劉徹輕笑一聲道︰“她倒是會選玩伴,這樣也好,開心些總比整天愁眉苦臉的強。劉勝,宗正卿怎麼說?”色色资源站无码AV网址   雲瑯熟練的揮動錘子,那些最近被經常彈出來的階梯,出來的很順利,太宰帶著好奇的老虎踩著這些階梯步步高升,就像走在去天國的路上。资源站最稳定的资源站   來到了一座不算大的廣場,雲瑯才明白了一個道理,水銀流動的時候是沒有聲音的,甚至感覺不到它們在流動,遠遠的看去,廣場上的江河湖海銀光閃閃,似乎是一整塊,走近之後,才會通過水銀上漂浮的發黑的朽木發現,這些江河湖海一直在運轉不休。   “我們還是挑選最好的,這一點不要學少爺,少爺聰慧,他輕易就能辦成的事情,我們就需要很久……”久草免费线资源站   阿嬌正好從角門走進來,一進到雲家,就看到了這一幕,她不由得笑著對大長秋道︰“好威風的婦人!”

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.
