How to correctly convert a static ip to a normal domain (for example, rdserver.no-ip.com)?

Question

Computer networks

I have a provider (Beeline KZ) that distributes dynamic ip addresses. Previously, by registering on no-ip.com and creating a host there, entering my ip of this session there, it turned out to be able to access my PC remotely. This has recently stopped working. I try both through the router (Zyxel Keenetic) and directly. A mini server appeared at home and it was necessary to make a VPN. And it is impossible to deal with ip. How can I properly convert a static ip to a normal domain (eg rdserver.no-ip.com)?
Help, maybe I'm just doing something wrong.

Answer 1

Try another DNS host, for example: www.dtdns.com
Routers usually provide a connection to DynDNS themselves, only the credentials must be registered

Answer 2

run tracert to some site and look at the ip addresses of the hops. it may very well be that you now have an ipv6 address.
