I need to delegate [a number of subdomains] to No-IP and keep the main site in Wix. Is that possible?
From this Wix Support article, it seems Wix allows you to point a domain at them via an A record while keeping DNS under your control or you can allow them to manage DNS directly for the domain.
The choice between these method of connecting the domain to Wix will have an effect on accomplishing your client's goal.
Assuming the client wishes to use No-IP as a dynamic DNS provider, you have a few options.
- Set up a redirect in Wix from the subdomain to the No-IP URL e.g. sub.noipdomain.com (this can potentially change the URL in the browser).
Set up a redirect in GoDaddy from the subdomain to the No-IP URL e.g. sub.noipdomain.com (this can potentially change the URL in the browser).
Purchase "managed" DNS services from No-IP so they can control the DNS for example.com directly and thus dynamically update sub.example.com via their update program. You will need to update GoDaddy's nameserver settings in this case.
As a suggestion, for the second Wix Pointing option, you also may want to investigate Namecheap FreeDNS. As its name implies, it is currently free and should provide the same basic functionality as the paid No-IP option above (they have a dynamic DNS client).
