A simple mDNS (Multicast DNS) client and server library written in Go. It enables publishing and discovering services on a local network without an authoritative DNS server, supporting peer-to-peer service discovery.

Use cases

• discover services on a local network without a DNS server
• publish a service via mDNS so others can find it
• implement zeroconf/Bonjour-style peer-to-peer discovery in Go
• find hosts running a specific service type like _foobar._tcp
• build local network device discovery for IoT or home networks

When to choose

• you need lightweight mDNS service discovery in a Go application
• you are building tools for office, home, or private infrastructure networks where multicast works
• you want a minimal, MIT-licensed library rather than a full zeroconf stack

When to avoid

• your application runs in cloud or shared infrastructure environments where multicast is blocked
• you need full DNS-SD features or cross-language support beyond Go
• you need active development and frequent updates
