IP Address Lookup
Instantly view your public IP address, ISP name, country, city, region, and approximate geographic coordinates. Useful for network diagnostics, verifying VPN connections, geolocation testing, and understanding your online presence. Also supports looking up any IP address for country and ISP information.
IPv4 vs IPv6
IPv4 — Internet Protocol version 4
32-bit address format: 192.168.1.1. Supports ~4.3 billion unique addresses. Now exhausted — all public IPv4 addresses are allocated.
IPv6 — Internet Protocol version 6
128-bit address: 2001:db8::1. Supports 340 undecillion addresses. Solves IPv4 exhaustion and includes built-in security features.
Privacy & Security Tips
- Use a VPN — masks your real IP and routes traffic through another location
- Check for leaks — WebRTC and DNS leaks can reveal your real IP even with a VPN
- Avoid public Wi-Fi — shared networks expose your device to snooping
- Use Tor Browser — bounces traffic through multiple relays for anonymity
- Your IP address can reveal your ISP and approximate city/region
What Info is Visible?
Every website you visit can see the following from your IP address:
- Your public IP address (not your local/router IP)
- ISP or hosting provider name
- Country and approximate city/region
- Approximate latitude and longitude (~city level accuracy)
- Your exact home address or identity (not visible)
Common IP Lookup Use Cases
VPN Verification
Confirm your VPN is working by checking if your visible IP has changed.
Geo-Testing
Test geo-restricted content by verifying what location your IP appears to be in.
Network Debug
Identify your public IP during network troubleshooting and firewall configuration.
Security Audit
Check what information is publicly accessible from your IP before sharing content.

Understanding IP Addresses and Network Identity
Every device connected to the internet has an IP address — a numerical label that identifies it on the network and enables communication with other devices. Your public IP address reveals your approximate geographic location, ISP, and connection type to every website and service you connect to. Understanding your IP address is essential for network troubleshooting, security auditing, VPN verification, and configuring firewalls, access lists, and geo-restricted services. Our lookup tool shows your public IP, ISP details, approximate location, and connection metadata instantly.
IPv4 vs IPv6: The Ongoing Transition
IPv4 provides approximately 4.3 billion addresses — a number exhausted long ago. IPv6 expands the address space to 340 undecillion (3.4 × 10³⁸) addresses, enough for every grain of sand on Earth. Despite being standardised in 1998, IPv6 adoption is still growing gradually as ISPs and cloud providers enable dual-stack support. Developers must ensure their applications handle both address formats correctly — especially DNS resolution, logging, and access control lists that parse IP addresses.
IP Intelligence and Security
IP geolocation data powers content localisation, fraud detection, and compliance with regional regulations. VPN users can verify their connection is properly masking their real IP. System administrators use IP lookups to investigate suspicious login attempts and trace the origin of network attacks. For domain-level investigation, use the DNS Lookup to check DNS records.
