About Network & IP Tools

Free online network and IP tools for system administrators, network engineers, and developers. Our network toolkit includes a My IP Address tool that shows your public IP and network info using browser-based geolocation, IP location lookup to find the geographic location of any IP address, IP address validator for both IPv4 and IPv6 format verification, IPv4/IPv6 address converter for format transformation, MAC address generator with random and vendor-prefix options, and a comprehensive port number reference covering all well-known, registered, and dynamic ports. Every tool runs entirely in your browser — except IP detection and location services which use public APIs without storing your data.

Frequently Asked Questions

Is my IP address stored or logged?

No. IP detection requests are made to public APIs (ipify, ipapi.co) which may log requests for rate limiting purposes but do not store your information. No data is sent to our servers.

What is the difference between IPv4 and IPv6?

IPv4 uses 32-bit addresses (e.g., 192.168.1.1) supporting about 4.3 billion addresses. IPv6 uses 128-bit addresses (e.g., 2001:0db8::1) supporting 340 undecillion addresses. IPv6 was created to solve IPv4 address exhaustion.

Do I need to install anything?

No. All network tools work directly in your browser. IP address validation, format conversion, MAC generation, and port lookups are fully local. Only IP detection uses a lightweight public API call.
