DNSBL delisting and removal

Use this page to check one IP address at a time. If the IP is currently listed, the plugin sends a delist request through this site’s configured DNSBL / Tools API token. After a successful request, it can still take a little while before all resolvers show the updated result.

Request DNSBL delisting

Enter an IP address and run the listing check first. The first answer comes from the configured DNS resolvers, and if they say the IP is listed the plugin continues with a token-backed background check before Delist is offered. You can then search again immediately or use Reset to start over. If you click Check if listed with a CIDR range in the first field, Advanced opens and takes over that range instead.

Advanced delist range (CIDR)

Optional: run a local DNS resolver scan for a small CIDR range before delisting it. The CIDR scan stays inside this WordPress site, and the CIDR value entered here becomes the authoritative scope for the later CIDR delist. Large ranges are blocked. Use /24 to /32 only.

The scan uses the configured blacklist zones in small local batches so the resolver side is not flooded.
