Is it possible to fix the external IP?

Question

Computer networks

Good afternoon! I work in the admin panel of the site and it is accessed via an external IP. At the moment, I have fixed the IP through my provider, but in the near future I am planning to move from place to place and, accordingly, my IP will change.
The difficulty is that at this time I will not have the opportunity to use the service of securing an external IP from the provider - often wifi will be shared.
Question: Are there any known services or other ways to fix your external IP?
Many thanks in advance to everyone!

Answer 1

https://ru.wikipedia.org/wiki/DynDNS
Most routers themselves are able to reach this service and get your dns

Answer 2

I use my vpn or proxy for this
