If you are using Nimbus to manage the DNS for your domain name then you can edit your domains DNS records from within your Nimbus client area.


First log in to the client area via the following URL - https://youraccount.nimbushosting.co.uk/clientarea.php 


Then click on Domains > DNS Management



Under "Manage Domains" select the domain name from the drop down list and click the "Go" button



You will be presented with a list DNS records which you can then update as required. To save your changes click the "Save Changes" button. 



The Types of DNS Records you can add/change:


A - Most commonly record, used to map hostnames to an IP address of the hosting server. The destination must be an IPv4 address.
AAAA - Same as an A record but for a 128-bit IPv6 address. The destination must be an IPv6 address.
MX - Maps a domain name to a list of mail servers for that domain. The destination must be an hostname.
TXT - This is an text based record, typically used for verification records, SPF records and DKIM records.
CNAME - Alias of one name to another: the DNS lookup will continue by retrying the lookup with the new name. The destination must be an hostname.
SRV - Generalized service location record, used for newer protocols instead of creating protocol-specific records such as MX. This type of record is typically required for MS Exchange/Office 365.
