DNS Lookup
Query DNS records for any domain name. View A, AAAA, MX, CNAME, TXT, NS, and other record types to diagnose DNS configuration issues or verify domain settings.
IP Location Lookup
Determine the geographic location of any IP address. See the country, region, city, latitude, longitude, timezone, and ISP associated with the address.

How It Works
When you visit WhatIsMyIP.bz, our server detects the IP address your browser uses to connect. This is the standard behavior of any web server -- every HTTP request includes the sender's IP address so the server knows where to send the response.
Our Technology Stack:
- IP Detection: Server-side detection of your public IPv4 and IPv6 addresses from the incoming connection
- Geolocation: Industry-standard GeoIP databases that map IP ranges to geographic locations, ISPs, and organizations
- DNS Lookups: Direct queries to authoritative DNS servers for accurate, real-time record data
- WHOIS Data: Queries to Regional Internet Registries (ARIN, RIPE, APNIC, LACNIC, AFRINIC) for IP registration details
Accuracy and Limitations
We strive for the most accurate results possible, but it is important to understand the inherent limitations of IP-based geolocation:
- City-level accuracy: GeoIP databases are typically accurate at the country and region level but may be off at the city level, especially for mobile and satellite connections
- VPN and proxy users: If you are connected through a VPN or proxy, the detected location reflects the server's location, not yours
- ISP data: ISP information is based on IP block registrations and is generally very accurate
- Real-time updates: We regularly update our geolocation databases to reflect the latest IP allocations and reassignments
