About
These tools query public hosts or DNS from the server to confirm resolution, certificates, headers, and ports. Results are what the CheckKit server saw then, and may differ from your machine or another region.
Why results may differ from your machine
DNS is cached and geo-aware, HTTP headers can change by CDN node, and port checks depend on firewalls and egress IPs. Treat this as a snapshot from one public probe, then compare with local nslookup or your browser.
Usage limits
Only probe public hosts you are allowed to check. Timeouts and failures are shown as-is. This is not a scanner or a monitoring archive.
What it is and is not for
Use these to confirm DNS, certificate expiry, HTTPS response headers, or whether a TCP port is reachable from the public internet. They are not port scanners, load testers, or firewall bypasses. Current Public IP shows the public address seen by this server, not your LAN NIC address.
