Nobody is forcing anyone to use RPZ. There are thousands of IETF documents covering a multitude of technologies, both real and imagined (just look at the avian carriers series). Personally I used to have issues with the concept of RPZ when it was first raised years ago, but my views have changed over time, though apparently you only discovered it a couple of weeks ago. In any case, like so many other technologies, it is a tool. People using RPZ do so for a variety of reasons and they should be free to do so. Many of us use DNSBLs to protect our users’ inboxes from spam, phishing and other junk. RPZ is a different tech, but in the end is just another tool in our toolbox. And please don’t bring Trump (or any other politician) into this. Apart from anything else this is a RIPE list not an ARIN one ☺ Regards Michele -- Mr Michele Neylon Blacknight Solutions Hosting, Colocation & Domains http://www.blacknight.host/ http://blacknight.blog/ http://ceo.hosting/ Intl. +353 (0) 59 9183072 Direct Dial: +353 (0)59 9183090 ------------------------------- Blacknight Internet Solutions Ltd, Unit 12A,Barrowside Business Park,Sleaty Road,Graiguecullen,Carlow,R93 X265, Ireland Company No.: 370845
