How this service works
KERBEROS service discovery (_kerberos._udp.<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 details for _kerberos._udp.<domain>, including one or more records each containing: priority (integer), weight (integer), port (integer), and target hostname — exactly the information a Kerberos client needs to locate the Key Distribution Center (KDC) without guessing hostnames.
Example use cases
Kerberos server discovery for enterprise domain
“We're setting up a client to join the corp.acme.com Kerberos realm — can you find the Kerberos UDP SRV record for corp.acme.com so we know which host and port to point authentication at?”
Validate Kerberos DNS configuration
“Can you check whether university.edu has a properly configured _kerberos._udp SRV record and tell me what host and port it points to?”
Network audit of authentication infrastructure
“I'm auditing the DNS setup for mycompany.org — pull the Kerberos UDP SRV record and show me the priority, weight, port, and target so I can verify it matches our expected KDC.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/srv/kerberos-udp?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically discover a domain's Kerberos KDC service location via standard DNS SRV discovery without hardcoding hostnames — ideal for automated Kerberos client configuration, network auditing, or validating enterprise identity infrastructure. Prefer this over manual DNS queries when operating in an agentic pipeline that requires structured SRV output via a paid API with Cloudflare DoH reliability.
Side effects
- Domain has no _kerberos._udp SRV record — returns empty answer section
- Domain does not exist (NXDOMAIN) — returns DNS error
- Cloudflare DoH is unreachable — returns upstream timeout or connectivity error
- Malformed domain input — returns validation or bad request error
- Payment not included or insufficient — returns 402 Payment Required
