Check this part of this guide, I use these DNS on my laptop and they are doing a pretty well job:

SAFE & PRIVACY DNS

About DNS, using those from your network provider (default) is not always the best choice. There are some more interesting alternatives:

• Cloudflare uses 1.1.1.1 and 1.0.0.1 for its DNS service over IPv4 and their name resolution services have some extra features for safety. It claims to be the fastest DNS in the world.
• AdGuard uses 94.140.14.14 and 94.140.15.15 and offers an {advertising, malicious, malware} hosts resolution name blocking feature plus family protections on 94.140.14.15 and 94.140.15.16 but they also offer an unfiltered service (check the link).
• Quad9 uses 9.9.9.9 and 149.112.112.112 to offer a service which a combination between the two above, in their claims (fast and safe).

The best choice is alternating two coherent DNS services together - for reliability - and using a caching system configured for leveraging a large DNS cache to gain speed, privacy and also safety depending the services you choose.

#IPv4 nameservers
nameserver  9.9.9.9 
nameserver  94.140.14.14
nameserver  149.112.112.112
nameserver  94.140.15.15

#IPv6 nameservers
nameserver  2620:fe::fe
nameserver  2a10:50c0::ad1:ff
nameserver  2620:fe::9
nameserver  2a10:50c0::ad2:ff

This is an example of /etc/resolv.conf for every host connected with an IPv4 + IPv6 network which alternates AdGuard and Quad9 ad-blocking and safe-filtered DNS .

Attention : usually the /etc/resolv.conf is not the right place to insert these values.
