Some products are assigned dedicated/static IP addresses. These products include dedicated Servers, Virtual Servers, Broadband Services, and some Hosting Packages. In some cases you may need to set a reverse DNS (PTR) record for an IP address assigned to you. This can be done from within the Customer Portal. When logged into the Portal, select 'My Services' choose the service that has the IP address assigned to it and if you can add your own reverse DNS records then you will see a menu called 'Reverse DNS'. This is where to add the required record. Usually you will also need to add a matching 'A' record in the DNS zone for the domain name used in the Reverse DNS record. You can check reverse records by using the 'dig' command on Linux and Windows PCs with the correct software installed, you may also find a number of websites offering a free DNS checking service..
