Reverse DNS: Difference between revisions

==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 ''"domainsDomains"'' 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 for the hostname. The value is not restricted to be just one single dnsDNS label; it could contain dots for subdomains. Then enter the ipIP 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 - ipv4IPv4 is correct in this example case.The procedure for ipv6IPv6 address reverse lookups is the same, just click the pop-out menu toand select "ipv6 reverse".
 
You can also amend existing records or delete them by first clicking on one entry in the list of records below so that it becomes highlighted. You can then either alter the details of the record and then click '''Apply''', or you can click an ‘Erase’ button on the right.
