Checks one IPv4 address against nine public DNS blocklists at once — SpamCop, UCEPROTECT, PSBL, Barracuda, DroneBL and four more — and returns each list's raw return code plus the reason text the list itself publishes, not a score. Every list is re-checked on each call with its RFC 5782 test entry, so a dead list or one that refuses queries comes back as unavailable instead of reading as clean. Includes the delisting URL for each hit.Overview
