CNAME update

Веб компанія надіслала таке повідомлення (мені треба людина, яка може зробити те, про що вони там пишуть): 

Here are the CNAME details for SuperGrad. Please pass the details below on to your domain manager so that they can update the settings prior to launch. If you want the site to be live first thing on 08/05/2018 then it's probably best to ask your domain manager to update the details the evening before as that will give the changes time to propagate. However, don't update the details before then or users will be able to access the new site before the launch date.

SuperGrad is set-up on Strategies' live servers and is ready to be made publicly available on 08/05/2018.

To make the site available you will need to make the following changes to the DNS settings on the SuperGrad domain...

Create or modify a new record called: www (or the sub-domain - i.e. jobs for a http://jobs.example.com domain)

Use the following CNAME address as the value: www-supergrad-org-uk.cname.strategiesuk.net

This needs to be entered exactly as it appears above (the hyphens are correct), with the possible exception of the dot on the end. This is required, but some DNS providers will automatically add this in.

To ensure that the site is accessible without the need to enter 'www' into the URL, please set-up a "301 redirect" on the apex record to the full website URL. If the domain management service doesn't offer/allow this you will need to set-up a new "A record" for the apex and use the following IP address as the value for it: 212.250.3.80. 

This IP address should NOT replace the CNAME record for the www domain. You also need to make sure you remove any other A records in place for the apex and www sub-domain.

In addition to the above changes, if you have an SPF record configured on your domain please add the following alongside your existing entries: include:spf.strategiesuk.net. 

This helps us to send emails like the 'jobs by email' and 'tell a friend' and 'registration' emails on your behalf.
