Welcome to SwiftBL

SwiftBL is a service that provides IRC administrators with an easy way to prevent malicious clients (open proxies/drones) from connecting and causing damage to their network. To do this we maintain a database of potentially abusive hostnames which are served via a DNS zone (dnsbl.swiftbl.net). Although the database is primarily aimed at IRC-related instances there is no reason why it can not be used in conjunction with other protocols (such as email).

Recent news

12th February 2009 - Backend changes

We are currently in the process of rewriting the majority of our backend software - parts of this website may become inaccessible at certain times, however any disruption caused should be minimal. We will also be making several design changes with new content being added over the next few weeks.

26th October 2008 - Brief downtime

Due to maintenance on one of our main servers we experienced a brief period of downtime. Full service has now been restored, and we apologise for any inconvenience caused.

22nd October 2008 - Database refresh & updates

The blacklist database has been purged of old/inactive entries to maintain our high level of accuracy. We have also begun the process of moving our main DNS server to another machine - no users should be affected as the old server will remain running whilst everything propagates. Finally, some changes will be made to this website over the next few weeks, including the creation of the database statistics page.

12th May 2008 - Changes/Updates

Following on from our recent name change (and server change) from Anoxs DNSBL we have (once again) re-designed the website. We've also taken this opportunity to update some of the content on the website and hopefully make it easier for those who are listed in the database to be able to remove themselves. We're still considering our options regarding the implementation of a service allowing users to submit their proxy reports (ie. using BOPM's dnsbl_to function) directly into our database, but if such a service was to be introduced it wouldn't be until after the summer.
