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):

有了實驗結論支持,2008年7月20日至9月20日北京奧運會殘奧會期間,北京實行了長達2個月的單雙號限行措施。為保障中國人民抗日戰爭暨世界反法西斯戰爭勝利70周年紀念活動期間北京市空氣質量,2015年8月20日至9月3日將再次實行單雙號限行。 施正文分析,上述舉措的提出,反映出我國財政部門在經濟形勢趨緊的前提下,正在厲行節約,對財政資金進行更加有效合理的使用。国产超级AV在线视频 此外,該區還將設立“越秀區外國人社會工作服務專項項目”,以政府購買服務方式開展涉外服務;在外國人較為集中的地區大力營造雙語(多語)環境,編印《外國人在穗指南》、制作視頻宣傳片,做好涉外出租屋管理法律法規的宣傳教育。(完)日韩亚洲电影av 在這575萬輛機動車中,目前新能源車只有2萬輛,而老舊機動車,其中包括國一、國二標準機動車及重型柴油車卻還有很大比重。統計,2014年,北京擁有國一及以下汽柴油車39.1萬輛,國二汽柴油車58萬輛,佔全市560萬輛機動車保有量的17.3%。 昨天,全國政協委員、北京市衛計委主任方來英接受京華時報專訪時表示,今年年底將實現非急診全面預約,改善病患就醫感受。同時,對于近期備受關注的“號販子”,醫衛部門將通過調整內部醫療衛生服務流程,來擠壓號販子的生存空間。此外,方來英建議將號販子入刑。激情色图 新華社客戶端已成為國內移動互聯網最權威的新聞發布平台,全國重大新聞首發率達到80%以上,下載量突破1.2億。作為首創的門戶客戶端,目前省、市、縣地方頻道簽約3109家,是全國最大的黨政頻道集群。

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.
