How to Use What's My IP Address
Open the tool to automatically detect your public IPv4 and IPv6 addresses, ISP, ASN, and approximate location in milliseconds.
Click "Copy IP" to copy your active public IP address to clipboard, or "Copy All Details" to copy a structured text manifest.
Check dual-stack connectivity by reviewing the live IPv4, IPv6 badges, and round-trip ping latency.
Use the Custom IP & Domain Lookup search bar to inspect any external IPv4, IPv6, or domain hostname (e.g., 1.1.1.1 or 8.8.8.8).
Inspect the IP classification card (Public, RFC 1918 Private, CGNAT, Loopback) to verify subnet architecture and NAT configurations.
What is an IP Address and How Does Internet Routing Work?
An Internet Protocol (IP) address serves as the digital postal code for devices connected to the global network. Every data packet sent across the internet contains a source IP (your device) and a destination IP (the target server). Routers along the transmission path inspect these headers and forward packets across interconnected Autonomous Systems (AS) until they reach their destination.
Understanding IPv4 vs. IPv6 Architecture
As the world ran out of unallocated IPv4 address pools, IPv6 was introduced to provide virtually unlimited addressing capacity, built-in network security (IPsec), simplified packet headers, and elimination of Network Address Translation (NAT) bottlenecks. Modern devices and ISPs often operate in Dual-Stack mode, carrying both IPv4 and IPv6 traffic simultaneously.
How IP Geolocation and ASN Routing Function
IP Geolocation databases correlate IP address ranges with physical routing facilities, exchange points (IXPs), and ISP regional data centers. While municipal-level accuracy is standard for metropolitan broadband, mobile cellular networks may route traffic through central regional gateways hundreds of kilometers away from your actual physical location.
Public vs. Private IP Address Ranges (RFC 1918)
Private IP addresses (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) are reserved for local area networks (LANs) and cannot be routed over the public internet. Your home router uses Network Address Translation (NAT) to translate multiple internal private IP devices into a single shared public IP address.
IP Address Privacy, Security, and Protection Best Practices
Your public IP address allows remote servers to detect your general geographic region and ISP. To safeguard your digital footprint against geo-blocking, DDoS attacks, or network tracking, consider using trusted VPN protocols (WireGuard/OpenVPN), enabling DNS-over-HTTPS (DoH), and verifying dual-stack leak prevention.
Frequently Asked Questions
What is a public IP address?
A public IP address is a globally unique numerical identifier assigned to your internet router or modem by your Internet Service Provider (ISP). It is the address visible to external websites, APIs, and online servers when your device communicates over the public internet.
What is the difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses formatted as four decimal numbers separated by dots (e.g., 192.0.2.1), providing approximately 4.3 billion unique addresses. IPv6 uses 128-bit addresses formatted as eight hexadecimal groups separated by colons (e.g., 2001:db8::1), providing 340 undecillion addresses to solve IPv4 exhaustion.
How is IP geolocation determined and is it 100% exact?
IP geolocation maps IP allocations to geographic locations using regional Internet registries (RIRs like ARIN, RIPE, APNIC) and ISP infrastructure nodes. It typically identifies your country, state/region, and city with high accuracy, but does NOT reveal your physical street address or exact room location.
What is an ASN (Autonomous System Number) and ISP?
An Internet Service Provider (ISP) is the company providing your internet access (e.g., Airtel, Jio, Comcast, Vodafone). An Autonomous System Number (ASN) is a globally unique identifier assigned to a network routing domain controlled by an organization or ISP using Border Gateway Protocol (BGP).
What is Carrier-Grade NAT (CGNAT / RFC 6598)?
Carrier-Grade NAT is a technology used by ISPs where multiple residential or mobile broadband customers share a single public IPv4 address. If your router’s WAN IP is in the 100.64.0.0/10 range, your ISP is using CGNAT, which can prevent direct inbound port forwarding.
Does my IP address reveal my identity or physical address?
No. An IP address only identifies the routing node of your ISP. It does not contain your name, email, street address, or phone number. Only your ISP can legally correlate an IP address with a subscriber account under lawful court subpoena.
How can I change or hide my public IP address?
You can mask or change your public IP address by connecting through a Virtual Private Network (VPN), using an encrypted proxy (Tor/SOCKS5), or restarting your home router if your ISP assigns dynamic IP addresses via DHCP.
Does Toolique store, log, or track my IP address?
No. Toolique is built on a strict privacy-first architecture. All IP queries are performed directly inside your client browser via HTTPS. Toolique servers do not log, persist, or monitor your IP addresses or network activity.
