How to edit Zone Records

The instructions below will assist you with modifying your domain zone file on our DNS.

To perform DNS forwarding/zone updates (changing A/MX/CNAME/TXT records), use the following steps:

- Log in to your account
- Go to "My Registered Domain(s)"
- Click on the domain name you wish to modify
- Under the heading "Domain Nameserver Details" select the 'Set Up DNS Record' option
- If the 'Set Up DNS Record' option is not visible please select the 'Use Instra's Nameservers' option and complete this change back to our default DNS first to enable other options (!! please be sure you want to switch to our name servers before doing so)
- Edit or Add records as necessary

* The parent domain does not need to be explicitly referenced in the 'Host' field; records for the bare domain should use the '@' host, for subdomain records only the subdomain should be entered (e.g. 'www')
* The 'www' and '@' hosts have separate DNS entries, if you wish for your website to display at both these hosts you need to update both records (e.g. update the A record entries with the same IP address)
* The content of all CNAME and MX entries must be finished with a dot. e.g. CNAME -
* If a CNAME record is entered for any host, no other records should be present for that host - i.e. never add a CNAME for the '@' host, always resolve this host via A record to an IP; '@' host CNAMES will break your zone
* MX priorities must be greater than 0 and are relative, not absolute, with the lowest-numbered records being most preferred
* SPF records should be added as 'Type' TXT as 'Type' SPF is now deprecated
* SRV records have a particular format; all the data for the records is entered in the 'Host' and 'Content' areas but if you need details on exactly how please let us know
