An IP address is a numerical label assigned to every device connected to a network that uses the Internet Protocol. Every request your browser makes includes your IP address so the server knows where to send the response. Knowing how to look up an IP address and understand the information associated with it is useful for network debugging, security analysis, and geolocation verification.
IPv4 vs IPv6
IPv4 addresses are 32-bit numbers written as four decimal octets separated by dots: 192.168.1.1. With only about 4.3 billion possible IPv4 addresses and billions of internet-connected devices, the pool of available addresses is exhausted. Network address translation (NAT) allows many devices to share a single public IP, which is why your home router has one public IP but all your household devices can access the internet simultaneously.
IPv6 addresses are 128-bit numbers written as eight groups of four hexadecimal digits separated by colons: 2001:0db8:85a3:0000:0000:8a2e:0370:7334. IPv6 provides approximately 340 undecillion unique addresses, enough for every device ever likely to exist.
What Geolocation Data an IP Reveals
IP geolocation databases map IP address ranges to approximate physical locations. The precision varies. For most consumer IP addresses, the lookup can reliably determine the country and region (state or province). City-level accuracy is less reliable, particularly for mobile networks and users behind VPNs. Street-level accuracy from an IP alone is essentially impossible.
The lookup also returns the ISP (Internet Service Provider), the organisation that owns the IP range (which for a business would be the company name), the autonomous system number (ASN), and sometimes the connection type (residential, commercial, datacenter, or mobile).
Practical Uses
Server log analysis: when reviewing server access logs, IP lookups help identify where traffic is coming from, flag unusual patterns, and attribute suspicious activity to a geography or network.
Fraud detection: IP geolocation is one signal among many used to detect potentially fraudulent transactions when the IP location does not match the billing address.
Content geolocation: some services use IP geolocation to serve location-appropriate content or to enforce geographic licensing restrictions.
VPN and proxy detection: geolocation databases often include flags for known VPN providers, Tor exit nodes, and data center IP ranges.
Using the DevHexLab IP Lookup Tool
Open the tool at /tools/developer/ip-lookup. Enter an IPv4 or IPv6 address, or leave the field blank to look up your own current public IP address. The results show the approximate location, ISP, ASN, and organisation.
Frequently Asked Questions
How accurate is IP geolocation?
Country-level accuracy is typically above 95 percent. City-level accuracy is much lower, often 50 to 80 percent depending on the database and the type of network.
Can I hide my IP address?
A VPN replaces your visible IP with the VPN server's IP. Tor routes your traffic through multiple relays, making the origin very difficult to trace. Both methods have limitations.
Is my home IP address static or dynamic?
Most residential internet connections use dynamic IP addresses that change periodically. Business connections often have static IPs. Check with your ISP.
Your IP address reveals less than many people assume but more than some people realise.
