## What it is
GeoDNS is an authoritative DNS server written in Go that returns per-client targeted responses based on the geographic location of the requester. It powers the NTP Pool project and supports JSON-based zone configuration with an HTTP monitoring interface.

## Use cases
- serve DNS answers based on client geography
- run geo-targeted authoritative DNS for my domains
- power a global anycast DNS service like NTP Pool
- direct users to the nearest server via DNS
- self-host a DNS server with per-region records
- return different IPs per country or region in DNS

## When to choose
- you need DNS responses tailored to client location
- you run a globally distributed service and want DNS-based traffic steering
- you want a lightweight, self-hosted authoritative DNS server in Go

## When to avoid
- you need a full-featured recursive resolver for end users
- you prefer managed DNS hosting without operating servers
- you need DNSSEC-heavy or highly complex zone management features

## Facets
- artifact type: service
- maturity: stable
- function: networking, routing, monitoring
- domain: networking, infrastructure-as-code, self-hosted, microservices
- platform: go, cross-platform, self-hosted
- tags: dns-server, geolocation, anycast, geo-targeting, authoritative-dns, load-balancing, linux
