查询IP地址信息、WHOIS数据、位置地图和网络详情。
An IP (Internet Protocol) address is a unique numerical identifier assigned to every device connected to a computer network that uses the Internet Protocol. IPv4 addresses consist of four numbers (0-255) separated by dots (e.g., 192.168.1.1), while IPv6 addresses are 128-bit hexadecimal numbers designed to address the exhaustion of IPv4 addresses.
IP lookup queries various databases including Regional Internet Registries (RIRs) like ARIN, RIPE, and APNIC. These organizations maintain records of IP address allocations, ownership information, and network details. WHOIS and RDAP protocols provide standardized ways to query this information.
IP geolocation accuracy varies. Country-level accuracy is typically 95-99%, while city-level accuracy ranges from 50-80%. VPNs, proxies, and mobile networks can affect accuracy significantly.
An Autonomous System Number (ASN) is a unique identifier assigned to a network that has its own routing policy. Large ISPs and organizations have their own ASNs for managing their IP address blocks.
