While there is several possibilities for setting up the DNS - with joker you leave it at the A record.
But as many users - if you tell them the web address - will be prepending the domain with www - it is best practice to have a CNAME record pointing to your root domain
When logged into your joker account
- Click DNS for your domain (in the domain list)
- Click Add New Record
a. Set Type field to A
b. leave Name(Subdomain) empty
c. enter your public IP in IP address
c. click Add - Repeat above - this time with CNAME
a. In Type - select CNAME
b. In Name - enter www
c. In Alias - enter *det-sovande-folket.org’
d. Click Add - Repeat for any email you want to add
a. Set Type to Email
b. Set the address e.g. brandent
c. Set an existing mailbox to receive the mail
d. Click Add
If you do not have a dedicated public IP - even the DHCP assigned addresses rarely change - you may need to use their Dynamic DNS service (which I have no experience with).
When you are done - Click Save changes at the page bottom.
DNS records created have a TTL (time to live) at 86400s - so waiting for a change to propagate can be a pain. Clicking options for the A-record - then the Edit icon - you can set TTL to e.g. 600s which is 10m. Remember to Save changes - otherwise the changes will not be saved.
