How this service works
KERBEROS service discovery (_kerberos._tcp.<domain>): SRV records with priority, weight, port and target host, from Cloudflare DoH. Tells a client where the domain's kerberos service lives without guessing hosts. $0.01 per lookup.
Output
Returns the SRV record data for _kerberos._tcp.<domain> including one or more entries with priority, weight, port number, and target hostname, along with TTL and DNS response code, as answered by Cloudflare DNS-over-HTTPS.
Example use cases
Kerberos KDC discovery for enterprise SSO
“We're setting up Kerberos-based single sign-on and need to know the KDC host and port for corp.example.com — can you pull the _kerberos._tcp SRV record for that domain?”
Verify Kerberos DNS config before deployment
“Before we go live, can you check that acme.internal has a valid _kerberos._tcp SRV record and tell me the priority, weight, port, and target host returned?”
Debug Kerberos authentication failure
“Users are reporting Kerberos login failures against university.edu — can you do a DNS SRV lookup for the Kerberos TCP service on that domain so I can see if the DNS record is pointing to the right server?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/srv/kerberos-tcp?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically discover the Kerberos KDC (Key Distribution Center) host and port for a domain via standards-compliant DNS SRV resolution, especially when you want answers from Cloudflare's reliable DoH resolver rather than the local system resolver. Ideal for automation pipelines, infrastructure checks, and cross-network lookups where local DNS may be unreliable.
Side effects
- Domain has no _kerberos._tcp SRV record (NXDOMAIN or empty answer section)
- Domain does not exist (NXDOMAIN)
- Cloudflare DoH upstream timeout or error
- Malformed domain input causing DNS query failure
- SERVFAIL response if the authoritative DNS server is unreachable
