An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves two main functions: host or network interface identification and location addressing.
IPv4 (Internet Protocol version 4) uses 32-bit addresses and is the most widely used version. IPv6 (Internet Protocol version 6) uses 128-bit addresses and was developed to replace IPv4 due to the exhaustion of available IPv4 addresses. IPv6 offers a vastly larger address space.
Most residential internet service providers (ISPs) assign dynamic IP addresses, which can change periodically or when you restart your modem/router. Static IP addresses, which do not change, are typically used for servers or businesses and often cost extra.
No. IP geolocation is an approximation. It can usually identify your city, region, and country, but it cannot pinpoint your exact street address or physical location.
