Forward / Reverse Domain Name System (DNS)
For a PDF version of the PNCP DNS Management User Guide, please use the link below.
What is the difference?
A forward DNS lookup will, when supplied with a domain name (for example google.com), return the IP address for the supplied domain. When you access Google, a DNS server is looking in its forward lookup zone for the IP address(es) of the site, and then returning them to you. This type of record is an A record, and is the most common one. A forward DNS lookup can contain other records, such as MX, C-Name, etc.
A reverse DNS lookup is used to lookup the domain name for a supplied IP address. You normally supply the IP address backwards and append .in-addr.arpa (more info at http://en.wikipedia.org/wiki/.arpa). This can be a useful feature to anyone, but it is particularly practical for those running an outgoing mail server.
A good tool for finding rDNS or normal DNS records is dig.

WarningPlease be aware that DNS can be a confusing and complicated system. If you get something wrong, you might experience problems such as bouncing emails sent to your domain, or even cause your domain's website to malfunction. We recommend you use the DNS manager with caution, and ONLY if you understand basic concepts in DNS management.
