How to set Cloudflare DNS in Airport Time Capsule? and How to go back to ISP DNS? Thank you!

Hello, Please I would like to set Cloudflare DNS ( and in my Airport Time Capsule. My ISP gave me a modem / router (which is in Bridge mode) and my Airport Time Capsule is my router.

I have tried changing DNS Servers as it shows in the photo attached but doesn’t seem to work because when I perform a DNS lookup, it shows me my Router ip as DNS. :man_shrugging:t2:

Please, I would also like to know how I can reverse everything and re-obtein my ISP DNS.

Could I please get same help? Thank you in advance.

The router most likely is acting as a bridge between devices and the real DNS server. You can test is CF is being used by going to and looking at “Connected to”.

Most routers will default to the DNS the modem provides if you remove your custom values, however, if it doesn’t, you might need to ask your ISP what they are or reset your router to have it use ISP default again.
