dnswl.org has partnered with MXTools for subscriptions to dnswl.org data. MXTools is a global leader in providing IP and Domain Reputation Data along with anti-abuse solutions to network operators across a wide range of markets.
MXTools adds dnswl.org datafeed services to their existing portfolio of IP-based blocklists.
Since the dnswl.org Self Service went live in mid December 2015, we got over 1’000 Self Service user signups, and these users created over 3’000 Change Requests. Of course we are happy about the great up-take of the Self Service in the community.
For years, an unknown number of users behind TOR exit nodes have been abusing dnswl.org resources. Apparently for every email they receive, they query dnswl.org via the web, using the search interface open to all users. This causes considerable load on our webservers, the database servers, and our network infrastructure, sometimes causing significant delays for legitimate users.
Starting in early November 2014, we took some additional measures to enforce the query limit on our free nameserver infrastructure of 100’000 queries per 24 hours per organisation. As a result, some people may get a “blocked” result in their spamfilter setup.
