How this service works
Is TCP port 464 (kpasswd) 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 kpasswd without running a scanner. $0.01 per check.
Output
Returns the port status as open, closed, or filtered for TCP port 464 on the given host, along with the connection time in milliseconds. If the host is behind Cloudflare's edge, the result is reported as inconclusive since Cloudflare answers on behalf of the origin.
Example use cases
Kerberos port exposure audit
“Is port 464 open on kdc.mycompany.net? I need to know if our Kerberos password change service is accidentally exposed to the public internet.”
Pre-deployment security check
“Before I go live, check whether port 464 is open or filtered on 203.0.113.45 — I want to make sure kpasswd isn't reachable from outside.”
Incident response port verification
“We got an alert that port 464 might be exposed on ldap-server.internal.org — can you check if that port is actually open from the internet right now?”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/ip/port/464?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, scannerless check of whether TCP port 464 (kpasswd) is publicly reachable on a specific host, particularly for security audits, compliance checks, or incident response, without setting up or running a dedicated network scanner. Prefer it over full port scanners when you need a quick single-port check at low cost ($0.01 per check) from an external vantage point (Cloudflare edge).
Side effects
- Host is Cloudflare-fronted — result reported as inconclusive because Cloudflare's edge intercepts the connection
- Invalid or unresolvable hostname — likely returns an error or filtered status
- Host actively blocks all probes — port may show as filtered rather than closed
- Network timeout — may report filtered if no response received within timeout window
