How this service works
Change watch for is port 88 open: runs the check, compares it with the result from your previous call for the same host (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.
Output
Returns the current open/closed status of port 88 on the target host, a boolean indicating whether the status changed since the last call, a diff of fields that changed with before and after values, and the timestamp when the state was last observed. Previous results are retained for 90 days for comparison.
Example use cases
Kerberos port availability monitoring
“Watch port 88 on my Active Directory server at 10.10.1.5 and tell me if it's opened or closed compared to last time — I need to know if Kerberos availability has changed.”
Unauthorized port exposure alerting
“Check if port 88 is now open on the host 198.51.100.22 and compare it with the last result — flag it immediately if something changed so I can investigate a possible misconfiguration.”
Scheduled infrastructure change detection
“Run a change watch on port 88 for the host vpn.mycompany.com and report whether the open/closed status has flipped since my previous check, including what changed and when it was last seen.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/watch/ip/port/88?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to detect state changes on port 88 (commonly used for Kerberos authentication) rather than just knowing the current state. It is ideal for scheduled monitoring workflows where you want to be alerted only when something changes, reducing noise compared to plain port-open checks. Prefer it over a simple port-open check when you need historical before/after context and change timestamps.
Side effects
- Host unreachable or invalid hostname returns an error or indeterminate port status
- No previous check stored (first call) means 'changed' may be undefined or false by default
- Firewall blocking the probe may return closed even if port is actually open
- Stale comparison if previous result is older than 90 days and has been expired
- Payment failure results in no check being performed
