What Is an SRV Record?

SRV (Service) records tell clients which host and port provide a particular service, such as SIP calling, XMPP chat, Microsoft 365 services or Minecraft servers. They include a priority, weight, port and target host.

When to Use It

When setting up VoIP, chat or game servers that rely on SRV discovery.
When a client application cannot auto-discover a server.

How to Use It

Enter the full SRV name, for example _sip._tcp.example.com or _minecraft._tcp.example.com.
Check the port and target host.

Understanding the Result

Lower priority values are tried first; among records with the same priority, weight decides how traffic is shared. The target must be a hostname with its own A or AAAA record, not a CNAME.

Limitations

SRV records live under underscore-prefixed names, so looking up the bare domain returns nothing - you must include the service and protocol labels.

Frequently Asked Questions

An SRV (Service) record defines the hostname and port for a specific service, along with a priority and weight for load balancing - commonly used for VoIP (SIP), chat (XMPP), and some game servers.

Most websites don't need one - SRV records are only required if you're running specific services (like SIP telephony or XMPP chat) that rely on DNS-based service discovery.

An SRV record has four fields: priority, weight, port, and target hostname - clients query it under a special name like _sip._tcp.example.com.
