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):

開頭一兩分鐘我還覺得極不自在。我們團里的人一個也沒有,既沒個伙 屋里我們兩人之間的空氣完全凝結不動。過了幾分鐘,這個昏暗的身影 才終于轉過身于,步履不穩地輕輕走來,仿佛走在很滑的地面上︰“少尉先 生,倘若這孩于有唐突之處,請您不要見怪,但是??您不知道,這些年, 人家讓她受了多少折磨??每次總換個法子,進展又緩慢得可怕,我也明白, 她失去耐心了。可是叫我們怎麼辦?總得什麼法子都試一試,不試不行啊。” 老人站在她女兒剛才離去的桌前,說話的時候,並不抬眼看我。他那雙 幾乎被灰色的眼瞼完全蓋住的眼楮直愣愣地望著桌面。像個夢游人,他把手 伸進開著蓋的糖罐,抓出一塊四方形的糖塊,捏在指頭里轉來轉去,毫無意 識地盯著看,又把它放開;他的舉動看上去有些像醉漢。他的目光一直盯著 桌面,收不回來,仿佛卓上有什麼特殊的東西把他的月光禁銅在那里。他無国产二区亚洲欧美 av12综合网 開。我立刻向她沖去,幾乎是用暴力把那驚詫不已的姑娘拉到一邊︰“請您 給我幫個忙!看在老天爺的份上,幫幫忙,告訴我,這是怎麼回事!” 終于門背後有一只還看不見的手把兩扇滑動門左右推開。向我迎面走來国产东方av影院 同情恰好有兩種。一種同情怯懦感傷,實際上只是心靈的焦灼。看到別人的不幸, 急于盡快地脫身出來,以免受到感動,陷入難堪的境地。這種同情根本不是對別人的痛苦 抱有同感,而只是本能地予以抗拒,免得它觸及自己的心靈。另一種同情才算得上真正的 同情。它毫無感傷的色彩,但富有積極的精神。這種同情對自己想要達到的目的十分清楚。 它下定決心耐心地和別人一起經歷一切磨難,直到力量耗盡,甚至力竭也不歇息。

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.
