DNS & Networking Utilities

DNS LOC Record Generator

Build syntax-compliant DNS LOC records. Configure latitude, longitude, altitude, precision, and copy BIND settings.

Network engineers, systems auditors, and infrastructure developers publish LOC records to log geographic server nodes. This local generator formats coordinate notations in compliance with RFC 1876 specs. When to use it: When declaring router locations, cataloging server centers, or configuring localized query routing. What it solves: Avoids format reversal spacing errors, incorrect decimal conversions, and BIND compliance bugs. Why it matters: System records require explicit DMS coordinate structures to map geo-locations accurately.

Record Parameters Breakdown

Host: Matches subdomain target or core root domain (@).

Latitude: North/South degrees minutes seconds references.

Longitude: East/West degrees minutes seconds references.

Altitude: Server elevation above ellipsoidal sea values.

Size / Precision: Spatial radius coverage metrics.

How DNS Location Records Resolve

This generator builds arpa zone strings. The validation logic structures the record naming conventions in compliance with RFC standards.

When client resolvers query LOC records, DNS servers look up the published coordinate values. By reversing longitude and latitude positions and matching ellipsoidal reference heights, systems determine the location of the host server.

Before & After LOC Record Examples

❌ Before (Missing LOC record coordinates)

Systems querying geographical coordinates receive empty DNS returns, preventing location auditing.

;; Query: dig LOC domain.com
;; ANSWER SECTION:
;; (Empty response returned)

✅ After (Active LOC zone mapping)

A syntax-compliant BIND LOC record publishes server coordinates successfully.

@ 86400 IN LOC 37 48 46.000 N 122 26 21.000 W 10m 1m 10000m 10m
;; Active geo-delegation

Industry Use Cases

Developer Workflows	SEO Strategies	Operations & Teams
Publish server geographical coordinates for network auditing.	Maintain secure server directories to ensure localized server discoveries.	Audit server infrastructure coordinates.
Format geographical BIND data columns.	Audit physical assets hosting locations.	Validate network locations inside BIND templates.

Common DNS LOC Mistakes

Incorrect Direction Parameters

Assigning incorrect directions (e.g. using North for South America coords, or East for West coordinates) relocates server coordinates to different quadrants of the globe.

Missing Unit Indicators

Omitting the trailing m (meters) symbol on size and altitude parameters in BIND formats, which throws parser errors during zone compiling.

DNS LOC Best Practices

Check Coordinates: Double-check coordinates on physical maps before publishing.
Add Unit Suffixes: Always append the m suffix to altitude and precision values.
Align Server IPs: Ensure LOC records map correctly to the server's public IP block.
Audit Settings: Periodically verify record values after data center migrations.

Frequently Asked Questions

What is a DNS LOC record and what is it used for?

A Location (LOC) record is a type of DNS record that specifies geographical coordinate metadata (latitude, longitude, altitude, and sizing precision) for hosts, domains, or network subnets.

How is latitude and longitude formatted inside LOC records?

LOC records express coordinates in Degrees, Minutes, and Seconds (DMS) followed by Cardinal directions (N/S for Latitude, E/W for Longitude). For example, "37 48 46.000 N 122 26 21.000 W".

What does the altitude parameter measure?

Altitude measures the vertical height of your server above or below the WGS 84 reference ellipsoid in meters. It is written with a trailing "m" suffix (e.g. "10m").

What do size, horizontal precision, and vertical precision mean?

Size defines the diameter of the geographical area containing the host (default is 1m). Horizontal precision defines the geographical uncertainty of coordinates, and vertical precision defines the altitude uncertainty.

Can LOC records improve network routing?

Yes. Certain localized routing protocols and spatial search indexes query LOC records to route clients to the geographically closest server node, reducing latency.

Are LOC records mandatory for domain setups?

No. LOC records are optional, informational resource records. Domain managers configure them on critical core servers for auditing, security compliance, or spatial services.
