RPKI / ROA Checker
Enter an AS number and a prefix to check whether that BGP announcement matches the published ROAs. Networks doing ROV (Route Origin Validation) drop routes with an “invalid” status.
See also: IP / ASN WHOIS and Looking Glass (route visibility in RIS).
The tool checks one ASN + prefix pair on demand. It deliberately does not monitor ROA changes or send alerts.
