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):

他們的快樂也感染了我。我心里暗想,他們的確是好樣的。這段時間我 沒打招呼也未作解釋就悄悄溜走了,他們竟然一點也不生我的氣。 可是我突然發出口令︰“停——住!慢步前進!”大家出乎意料地一把 勒緊韁繩。全排活像一架突然急剎車的機器,用比較遲緩的步伐前進。輕騎 兵有點驚愕地斜眼瞟我。因為——他們了解我,也知道我那控制不住的跑馬 欲——平時我們總一口氣飛馬狂奔越過草地,直達做了標記的練兵場。然而 我覺得,仿佛有一只陌生的手猛地一把拉住我的韁繩︰我忽然想起了一件事 情。我想必是無意識地在地干線的邊緣看見左邊那片圍牆構成的白色方框, 府邸花園里的樹木和高塔的平頂,于是像有一顆子彈打中了我的心口︰也許 有個人正在那兒望著你呢!你曾經以你的跳舞狂傷害過這個人,如今你又用 你的跑馬欲重新傷她的心。這個人雙腿癱瘓,被緊緊地拴住,看見你像小鳥 一樣輕快地向前飛馳,會對你艷羨不止的。反正突然之間我因為自己這樣健影音先锋播放器日夜撸 等她訂完貨轉身要走,格羅斯邁耶先生趕緊搶到前面給她開門。我的藥 劑師先生?也從座位上站起,恭恭敬敬地向這位從旁飄然而過的姑娘問好。她 以雍容大方的態度客氣地致謝。好 家伙,好一雙天鵝絨一樣的褐色小鹿眼楮!亚洲日夜撸日日夜夜 ? 卡薩諾瓦(1725—1798)︰意大利冒險家,善于追逐女性,這里以此諷刺伏林斯基上尉。日夜撸 影音先 半個鐘頭到城外去。根據感情交叉反應的秘密法則,一個發火的人不自覺地 總要把他的火氣發泄到不相干的人身上,總像一個彈子球自己受到撞擊之後 總要傳到別的彈子上去。同樣,我的惡劣情緒不是針對約茨西和費倫茨,卻 去怪在汗克斯法爾伐一家身上。讓他們就等我一回吧!我叫他們看看,我不 是用禮品和殷勤款待所能收買的,我不會像按摩師或者體操教師那樣按鐘點 準時來到的。千萬別創造出先入為主的先例,養成習慣便成了義務,我可不 願把自己拴在某個義務上。我這愚蠢的倔強脾氣使我在咖啡館里坐了三個半 鐘頭,白白浪費了時間,一直呆到七點半,僅僅為了說服我自己並且證明我 是完全來去自由的,我愛什麼時候來去由我自己決定,開克斯法爾伐家的好 吃好喝和高級雪茄對我全都可有可無。

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.
