How this service works
NTP service discovery (_ntp._udp.<domain>): SRV records with priority, weight, port and target host, from Cloudflare DoH. Tells a client where the domain's ntp service lives without guessing hosts. $0.01 per lookup.
Output
Returns one or more SRV records for _ntp._udp.<domain>, each containing: priority (integer for server preference ordering), weight (load-balancing weight), port (UDP port the NTP service listens on), and target host (FQDN of the NTP server). If no SRV records exist, returns an empty result or NXDOMAIN indication.
Example use cases
Locate corporate NTP service endpoint
“Find the NTP server details for acme-corp.com — I need the SRV record showing the host, port, priority, and weight so I can configure our time sync clients.”
Verify NTP SRV DNS configuration
“Does cloudflare.com have _ntp._udp SRV records set up? Pull the SRV records and tell me what target host and port they point to.”
Discover NTP host before network setup
“Before I set up our new office network, can you check what NTP service my-isp-domain.net publishes in its DNS SRV records? I need the hostname and port.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/srv/ntp-udp?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover a domain's NTP server location programmatically via DNS service discovery rather than guessing conventional hostnames like 'ntp.domain.com'. Ideal for automated infrastructure configuration, network provisioning scripts, or verifying NTP SRV record presence. Prefer over manual DNS tools when you need structured SRV data (priority, weight, port, target) returned in a machine-readable format.
Side effects
- Domain has no _ntp._udp SRV records configured — returns empty answer section
- NXDOMAIN if domain itself does not exist
- Cloudflare DoH upstream timeout or error
- Invalid or malformed domain name input
- Payment failure (x402) if USDC balance is insufficient
