Can I remove my ISP ip address

Hi, I have successfully migrated from using a self hosted reverse proxy and all the incumbent holes in my firewall to using a Cloudflare Zero Trust Tunnel. So can I now remove all references to my IPS IP address from my Cloudflare DNS configuration just leaving the Cloudlfare tunnel IP address and the A records for services that can be connected to via my tunnel?

Thanks for any assistance

After you have migrated using Zero Trust tunnel you can remove the references to your self-hosted reverse proxy’s IP address from DNS configuration. You should update your DNS records to point to the correct IP address.
After updating the DNS records make sure that the traffic for the specific services that you want to access is set correctly, and review firewall rules and access controls to make sure that is aligned with the new configuration, making sure that the traffic will flow through.
