You will need to login to your iwantmyname account and go to the dashboard of the domain you want to connect to Wix.
DNS records setup
Wix does not have standard DNS records for all customers, so you we cannot set up an install. You will need to copy the DNS records in your Wix account.
There is an A record and a CNAME record. You can add those and save the changes in your dashboard, or if you send us the records via our support form to provide security authentication as the account holder, we can add them for you.
The records will look something like the example below.
We recommend using Wix's DNS records particularly if you are also using additional services, like email hosting.
Once the setup is complete in your iwantmyname account, you can finish the setup in your Wix account. Their instructions are here: Connecting a Domain to Wix Using the Pointing Method.
Nameservers setup
Alternatively, if you prefer you can use Wix's nameservers instead of DNS records. You can also find those in your Wix account. Like the DNS records, the nameservers are different for all customers, so you will have to copy yours in your Wix account. There are instructions here on how to find them: Connecting a Domain to the Wix Name Servers.
The records will look something like the example below. You do not need to copy the IP address that's in bracket's following the nameserver, just the part ending in ".net".
In your iwantmyname domain's dashboard, click on update nameservers, then delete all four of ours from the list. Replace them with the Wix nameservers. It's okay that there are only two. Do not leave any iwantmyname nameservers in place or it will cause a conflict. Then save the settings.
Then you will go back to your Wix account and complete setup there using the instructions linked above.
You may see things start working within a few minutes, but please remember that it can take up to 48 hours for DNS changes to fully propagate around the internet. So your website may not show up in all browsers immediately.
