I recently bought a new domain from namecheap and decided to delegate it to Yandex.Connect services, so I changed namecheap's DNS to custom, added Yandex' nameservers (
dns2.yandex.net) in the control panel, added the proof and within a couple hours my domain was being managed by Yandex.
Since I am hosting a personal site in my own premises and since my ISP doesn't sell any static IPs I decided to use DDNS. But when I tried to add a CNAME for
@ that points to
my-domain.example-ddns.org I found out it does... nothing. The record just isn't being created. I tried adding another one for a subdomain and it works perfectly fine.
After reading Yandex' guides I read this:
CNAME. Remember that a CNAME record can't be set up for the domain root, because this is prohibited by the RFC.
Imagine my shock when I read such a thing, when at the same time I have another domain registered with namecheap, but using namecheap's basic DNS instead, where I set up a CNAME record for @ that points to
my-other-domain.example-ddns.org and it works perfectly fine!
How do I work around this? Using an A record is a no-go since I can't get an static IP.
