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):

于是我又走進花店,取出一張名片,寫上︰“敬請原諒。”不行——這 怎麼可能!這一寫可就是我干的第四件荒唐事了,為什麼還叫人想起我干的 蠢事?然而不寫這個又寫什麼呢?“深表真誠的遺憾”——不行,這更要不 得,末了她會以為這遺憾是針對她說的。所以最好不加任何附言,什麼也不 寫。 我當時是怎麼回家的,今天我已經記不清了。我只記得,回家第一件事 便是一把拉開櫃子,那兒放著一瓶我為客人準備的斯利波維茨燒酒,我一口 氣灌下去兩三大杯,壓一壓嗓子眼里那股討厭的惡心的感覺。然後我就和衣 倒在床上,身上穿著原來的衣服,設法細細思索一下。可是在黑暗中我頭昏 腦脹,奇思怪想紛至沓來,猶如溫室里的花卉加溫過度而瘋長,在悶熱的土 地上長得亂七八糟、光怪陸離,變成刺眼的攀緣植物,使人窒息。在我那熱国产二区亚洲欧美 av12综合网 國說起。 “我還得謝謝您送的那些非常美麗的鮮花??這些花的確美極了,您瞧 瞧,插在花瓶里多好看啊。另外??另外??我也得請您原諒,我那天很夫 態,真愚蠢。??我那天的行為實在可怕??整整一夜我都沒有睡著,我實 在羞愧極了。實際上您是一番好意??您怎麼可能預先感到呢。再說”——国产东方av影院 後面,伊羅娜剛才出去的那扇門,開始輕輕地在鉸鏈上轉動起來。艾迪 特就像被人當場捕獲似的,急急忙忙地把匣子砰地一聲使勁關上。現在她對 我說的話,听上去就像是道命令︰

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.
