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):

  鬼奴們對于伙伴的消失,或者死亡似乎並不是很在乎,只是單純的為自己還活著歡呼,只有雲瑯清楚地知道,第一批來到鉤子山挖洞的五十六個鬼奴,到現在,只有兩個人還活著。   這就像荒原上的鬣狗一般,不殺它,它處處惹人厭,處處禍害別人。日本色情视频   一千人的騎兵軍陣,交鋒僅僅是一剎那的事情,當霍去病殺透敵陣的時候,眼前豁然開朗。亚洲欧洲无码在线   面對那些奔逃的同伴,為首的一個騎兵居然用自己的狼牙棒用力的敲碎了一個逃兵的腦袋,剩余逃兵也在一瞬間就被重新涌上來的騎兵殺的干干淨淨。   就像裴炎說的那樣,一個家想要振興,僅僅是活動在一個小範圍的圈子是沒有什麼用處的。日本色情电影 无码av高清毛片在线看   胡子花白的老將一巴掌拍在雲瑯的肩膀上大笑道︰“就是身子單薄一些,只要好好地打磨兩年,該是一只能看門的狗!”

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.
