What is the issue you’re encountering

I want to config Cloudflare DNS location DoT in my Asus router. The Asus setting dashboard required me to input the domain and IP address. I wonder if the IP address of the domain is static.

What steps have you taken to resolve the issue?

About two weeks ago, I used nslookup to check .cloudflare-gateway.com, and remembered the IPv4 and IPv6 address of this domain. Now I rechecked it using nslookup, and found that the two IPv4 addresses and two IPv6 addresses remain same. So are these IP addresses static and will not change?

If I set this DoT server on my Asus router, but the IP address change later, this will cause the DNS server in my router stop working. (Asus router requires me to input both the domain and the IP address)

You should see the associated IPv4 and IPv6 addresses in the dashboard:
