Check My IP Address Instantly – IPv4 & IPv6 Lookup Tool

An IP (Internet Protocol) address is a unique number assigned to every device connected to a network. It works like a digital home address, enabling data to travel across the internet to the correct destination. IPs come in two main forms: IPv4 and IPv6.

For example, geolocation services use your IP address to estimate your region. Your IP also helps websites identify your ISP and route content efficiently. Because of this, IPs play a major role in tracking and online privacy.

IP addresses are allocated by Internet Service Providers (ISPs) via global and regional authorities. Most users receive a dynamic IP that changes regularly. Businesses or advanced users may use a static IP that remains fixed.

Inside a home or office network, routers assign private IP addresses to each connected device using DHCP.

Public IPs are visible on the internet and assigned by your ISP. They identify your entire network externally.

Private IPs are only used within your local network and are hidden from the internet. Your router translates them to your public IP via NAT (Network Address Translation).

Your IP address can expose your location, ISP, and be used to track your Browse behavior. Advertisers, websites, and services often use IP geolocation to personalize content, target ads, or block access by region.

Using a VPN or proxy helps hide your real IP, enhancing your privacy and anonymity online.

Yes. Private IPs are not reachable from the public internet, reducing the risk of direct attacks. They’re protected by the router's firewall and NAT configuration.

However, full protection still requires encryption (e.g., VPN), strong passwords, and updated software within your local network.

IPv4 uses 32-bit addresses (e.g., 192.168.0.1) and allows around 4.3 billion unique addresses. IPv6 uses 128-bit hexadecimal addresses (e.g., 2001:0db8::1), supporting an almost unlimited number of devices.

IPv6 was developed to overcome IPv4 exhaustion and offers better efficiency and scalability.
