Hello @Paul Mckenna ,
I believe you are looking for something like 301 (Permanent) redirect service for apex (naked) domains.
For e.g:
(1) The root domain (example.com) should 301 (permanent) redirect to the www CNAME (www.example.com)
(2) The www CNAME (www.example.com) should direct to the external website (other.com)
URL redirect services aren't a DNS service. They work at the HTTP level rather than the DNS level. Some DNS providers bundle a URL redirect service as part of their overall offering. This service isn't currently supported by Azure DNS.
The URL redirect feature is tracked in the Azure DNS backlog. Use the feedback site to register your support for this feature.
Please refer : https://learn.microsoft.com/en-us/azure/dns/dns-faq#does-azure-dns-support-url-redirects
Kindly let us know if you need any further assistance on this issue from our end.
