How to configure reverse DNS

Introduction

With reverse DNS (rDNS) you link an IP address to a subdomain. This is the opposite of regular (forward) DNS where you link a domain to an IP.

Reverse DNS is used, among other things, to find out where an e-mail message comes from. This adds an extra layer of security to e-mail. Many e-mail servers are configured to reject e-mail or mark it as spam more quickly, if no valid rDNS is set for it.

You can manually configure your reverse DNS settings in our client area.
