News has arrived

We are very happy to announce that we’ve launched the first public BETA of RBLmon!

This is an online service which enables you to monitor your IP addresses against the most popular and commonly used DNS blacklists.

BRBL is now available

Today we added the Barracuda Reputation Block List (BRBL – pronounced “bahr-bel”) to our Multi-RBL checking tool. The latter now scans through a total of 52 blacklists.

RBL Check Update

We are glad to announce a major update on our Multi-RBL Check utility. We’ve removed some dead RBLs and added a bunch of new ones. The Multi-RBL Check now crawls through a total of 51 active blacklists.

RBL no longer online

Earlier this month the blackhole list stopped its operations. The reason for this, as announced by the UCEB team, is that their DNS infrastructure has been suffering persistent attacks.
