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):

……伊人综合合线在线 你上次信中分析他的話,我不敢下任何斷語。可是世界上就是到處殘缺,沒有完善的人或事。大家說他目前的夫人不太理想,但彌拉的母親又未嘗使他幸福。他現在的夫人的確多才多藝,精明強干,而連帶也免不了多才多藝和精明強干帶來的缺點。假如你和其他友人對你岳父的看法不錯,那也只能希望他的藝術良心會再一次覺醒,提到一個新的更高的水平,再來一次嚴格的自我批評。是否會有這幸運的一天,就得看他的生命力如何了。人的發展總是波浪式的,和自然界一樣︰低潮之後還有高潮再起的可能,峰回路轉,也許“柳暗花明又一村”,又來一個新天地呢!所以古人說對人要“蓋棺論定”。色欲天香天天影视综合 婷婷五月色综合

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.
