Message-ID: <20030916091303.GU9192@mea-ext.zmailer.org> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Or rather.. lattest thing to raise its ugly head is dorkslayers.com which in itself, and in all its subdomains ("*.dorkslayers.com") points to Verisign's web service. (Properly functioning lookup routines would ignore A-records with wrong kind values, and lacking TXT entries, but obviously I see cases where still present lookups do use faulty premisses.) None of the "free service" DNS BLs appear to have very long life-times. The technology has some usefull ideas behind it, but alas once some free service becomes popular, it is prone to overload, receive litigation threats ("wonderfull" usa..) and fold over. Often the folding is accompanied with a period of poisoned datasets. /Matti Aarnio -- co-postmaster of vger.kernel.org
