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):

‘有病’這兩句話,一個有良心、負責任的正派醫生就不應該說出口,試問 疾病從哪里開始,而健康又在哪兒結束?更不用說‘可以治愈’、‘無法治 愈’了!當然,這兩句話是廣為應用的,在實際生活中沒有這話不行。但是, 您永遠也別想讓我把‘無法治愈’這四個字說出口。我絕不說!我知道,上 世紀最最聰明的人尼采?曾經寫下了這句可怕的話︰最好不要做身患不治之癥 者的醫生。在尼采交給我們解析的那些前後矛盾、內容危險的句子里面,這 差不多是最最錯誤的一句話了。實際上正好反其道而行之才對啊。我要說, 要做醫生,恰好要做身患下治之癥者的醫生,甚至更進一步;一個醫生,只 有在所謂的身患不治之癥者的身上才能受到考驗。一個醫生如果一開頭就接 受了‘無法治愈’這個概念,他就拋棄了自己的使命,當了逃兵,臨戰之前 已經繳械投降。不消說,我也知道,在某些情況下干脆說聲‘無法治愈’, 帶著無可奈何的表情,揣上出診的酬金,轉身走去,要簡單得多,方便得多亚洲欧美综合中文 ——他也不知道自己是怎麼搞的,突然感到有個念頭,有個願望急于脫口而 出。亚洲图片欧美图片 即使在彌撒完了以後,我們又扶著艾迪特回到車上,她還久久地沉思默 —這種記憶力似乎和我有關私事的記憶力截然分開,在我頭腦里像軍人一樣 嚴格地起作用——使我立刻想起,今天安排了一種特別的操練。樓下已經號 角齊鳴,戰馬踏著馬蹄,清晰可聞,從勤務兵一再催促的樣子我看出,想必 已到動身出發的緊要關頭。我猛地一下子穿上已經擺好的軍裝,點上一支煙, 一陣風似地沖下樓梯,跑進院子,一轉眼就已經和列隊待發的騎兵中隊一起 催馬出發了。亚洲性爱网 這時,我們已經離火車站很近了。我們的談話很快就會結束;所以我急 急地問道︰

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.
