About the SRV Record Lookup Tool
The SRV Lookup tool queries DNS Service (SRV) records for a domain across the most common services (SIP, XMPP, Matrix, LDAP, Kerberos, Autodiscover, CalDAV, CardDAV, Minecraft) and any custom `_service._proto` label you provide. SRV records let a client discover both the hostname and the port of a service via DNS, plus a priority and weight for load-balancing — the RFC 2782 pattern that predates SNI and is still how enterprise mail, VoIP, XMPP and gaming clients bootstrap.
For every service we auto-check, we build the canonical `_service._proto.domain` label (for example `_sip._tls.example.com`) and issue a DoH SRV query. Results are sorted by priority ascending and weight descending — the order a well-behaved SRV client will actually try them. We surface priority, weight, port, target host and TTL for each answer, so operators can validate that failover and load-balancing behave as designed.
Use SRV Lookup when configuring Microsoft 365 or Exchange Autodiscover, verifying an XMPP or Matrix federation, publishing SIP or SIPS for a VoIP PBX, exposing a Minecraft server, or debugging why a client is picking the wrong backend. Pair with our DNS Propagation Checker to confirm SRV changes have replicated worldwide.
