How this service works
STUN service discovery (_stun._udp.<domain>): SRV records with priority, weight, port and target host, from Cloudflare DoH. Tells a client where the domain's stun service lives without guessing hosts. $0.01 per lookup.
Output
Returns one or more SRV records for the _stun._udp.<domain> DNS name, each containing priority, weight, port number, and the target hostname of the STUN server. If no SRV records exist, returns an empty or negative response.
Example use cases
WebRTC app STUN server discovery
“I'm building a WebRTC app and need to know what STUN server example.com uses — can you look up its _stun._udp SRV records and give me the target host and port?”
Diagnosing NAT traversal setup
“We're having trouble with peer-to-peer connections on our platform at mycompany.io — can you check what STUN server is configured by looking up the _stun._udp SRV records for that domain?”
Verifying STUN configuration after DNS change
“I just updated the DNS for voipplatform.net — can you look up the _stun._udp SRV records to confirm the STUN server is pointing to the right host and port now?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/srv/stun-udp?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically discover a domain's STUN server configuration via DNS without guessing hostnames. Prefer this over manual DNS lookups or generic DNS tools when you specifically need _stun._udp SRV records for WebRTC, VoIP, or NAT traversal applications. It is ideal for agents automating infrastructure checks, network diagnostics, or service configuration validation.
Side effects
- Domain has no _stun._udp SRV records — returns empty result set
- Invalid or non-existent domain — DNS NXDOMAIN response
- Cloudflare DoH upstream timeout or error
- Malformed domain input causing query failure
- Domain exists but STUN SRV record is misconfigured or points to unreachable host
