Understanding Your Results

Converts decimal coordinates to degrees, minutes, seconds, and cardinal directions (N/S, E/W), formats altitude, size, horizontal and vertical precision in meters, and generates valid BIND 9 zone records.

Practical Guidance & Next Steps

DNS LOC records are commonly used by NTP pools, distributed server farms, and amateur radio operators to locate nodes geographically without querying third-party IP geolocation APIs.

What is this?

A network utility that constructs RFC 1876 DNS LOC records containing physical geographic coordinates for hostnames.

How does it work?

1. Choose a city preset or enter latitude and longitude. 2. Configure altitude, object size, and horizontal/vertical precision. 3. Copy the formatted BIND zone entry or raw RDATA string.

Why use it?

Provides an authoritative, protocol-standard way to embed node physical locations directly into DNS.

Technical Scope & Calculation Limitations

Implements the RFC 1876 DNS LOC resource record specification.

Frequently Asked Questions

RFC 1876 defines the LOC resource record type, allowing domain names to publish their geographical coordinates (latitude, longitude, altitude, and precision) in DNS.
