How this service works
Is TCP port 69 (TFTP) open on a host? Attempts a connection from Cloudflare's edge and reports open/closed/filtered with the connect time; Cloudflare-fronted hosts are reported as inconclusive because their edge answers for them. Exposure checks for TFTP without running a scanner. $0.01 per check.
Output
Returns the port status as open, closed, or filtered along with the TCP connect time in milliseconds. If the host is behind Cloudflare's edge, the result is marked inconclusive because Cloudflare answers on behalf of the origin. Gives a clear signal for TFTP exposure without requiring a local port scanner.
Example use cases
Security audit for TFTP exposure
“I need to verify that port 69 is not exposed on our public server at infra.mycompany.com — can you check if TFTP is accessible from the internet?”
Network hardening pre-deployment check
“Before we go live, can you check whether TCP port 69 is open on 203.0.113.42? We want to make sure TFTP isn't accidentally exposed.”
Incident response TFTP investigation
“We got an alert that TFTP might be running on 198.51.100.15 — can you check if port 69 is actually open on that host right now?”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/ip/port/69?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, remote check for TFTP (port 69) exposure on a host without deploying your own scanner infrastructure. Ideal for security audits, pre-deployment hardening checks, or incident response when you suspect an unintended TFTP service is running. Prefer this over general port scanners when you want a lightweight, pay-per-check API call from Cloudflare's edge. Note: not suitable for hosts fronted by Cloudflare, which will return inconclusive results.
Side effects
- Cloudflare-fronted hosts return inconclusive result because Cloudflare's edge intercepts the connection attempt
- Firewalls that drop packets (rather than reject) may cause a timeout and be reported as filtered rather than closed
- Hosts with rate limiting may cause false filtered results
- Invalid or unresolvable hostname returns an error
- Temporary network issues from Cloudflare's edge may cause transient failures
