==Defining a reverse lookup entry on our control systems== |
==Defining a reverse lookup entry on our control systems== |

For example suppose you have an address from us such as <code>198.51.100.10</code> and you wish to define a PTR mapping (reverse lookup) to the name <code>fred-workstation.your-domain.example.com</code>.Important: If this domain is not hosted by us, you must first have asked staff to set up <code>your-domain.example.com</code> in our control system, but you only need to do so once. Then you would go into our control panel system, go to ''"Domains"'' and select the entry <code>your-domain.example.com</code> which we will have added for you following your request. Now for each individual reverse lookup entry you wish to define, enter for example the name <code>"fred-workstation"</code> into the first edit box. The value is not restricted to be just one single DNS label; it could contain dots for subdomains. Then enter the IP address in the edit box below, in this case <code>198.51.100.10</code>. You must remember to then click '''OK''' or '''Apply''' to create the record. You will see that a new record is now listed below. |

Notice there is an option to select "ipv4 reverse" or "ipv6 reverse" lookup - IPv4 is correct in this example case. The procedure for IPv6 address reverse lookups is the same, just click the pop-out menu and select "ipv6 reverse". |
