My local registrar (isnic.is) has informed me that on of your name servers (ns2.wordpress.com) is not providing a valid PTR record. I'm currently using ns1 and ns2 servers as DNS and I have tried to switch to ns1 and ns3 but I always get answer from the ns2 server when validating my settings at my registrar. Is it possible that you must clear some Zone settings (remove ns2.wordpress.com) prior to my changing the DNS register? Could you please take a look at this for me?
