SRV Records Explained

What is an SRV Record?

An SRV (Service) record specifies the location of specific services in your domain. It allows you to define the hostname, port number, priority, and weight for services like SIP, XMPP, LDAP, and others.

Common Uses

• XMPP (Jabber) server configuration
• SIP and VoIP services
• Microsoft Active Directory services
• Load balancing and failover configuration
• Service discovery in distributed systems

Best Practices

• ✓
  Use meaningful priorities

  Set appropriate priority values to ensure proper failover behavior (lower numbers are tried first).

• ✓
  Configure weights correctly

  Use weight values to distribute load among servers with the same priority.

• ✓
  Follow naming conventions

  Always prefix service names with underscore (_) and use standard protocol names.
