Free SRV lookup

Look up SRV records. Enter the full name, such as _sip._tcp.example.com, or a domain plus a service.

Lookups use Cloudflare 1.1.1.1 from your browser.

The name is not the domain

An SRV name has the shape _service._protocol.domain. SIP, XMPP, Minecraft, LDAP and Microsoft Autodiscover all use different service labels. Looking up the bare domain returns nothing, which is correct.

Priority, weight, port, target

Clients try the lowest priority first. Weight splits traffic between records that share a priority. The port is part of the record, so the service can move ports without changing the client.
