You need to specify two DNS servers—one main and one backup—for your pfSense setup. This helps the router find domain names and ensures continuity if the primary fails. It doesn’t do anything extra beyond guiding DNS resolution.

It shows how to find domain names. You should use at least one option. Consider OpenDNS at 208.67.222.222 and 208.67.220.220, Google DNS at 8.8.8.8 and 8.8.4.4, or Quad 9 at 9.9.9.9.

DNS acts as the bridge between IP addresses and human-readable names. For instance, instead of entering a numeric IP like 1.2.3.4 to access a website, you can simply type its name, such as google.com, which directs you there. Popular DNS servers for IPv4 include Cloudflare and Googles Cloudflare: 1.1.1.1, Google: 8.8.8.8 or 8.8.4.4

If left empty, the ISP usually assigns it automatically. I wouldn't do that since most providers redirect your browsing, which could send incorrect searches to their search engine. There are many public DNS options available. For my use, I prefer 9.9.9.9 - Quad 9 8.8.8.8 - Google as a backup.

DNS stands for "Domain Name System," acting as a map linking domain names to IP addresses. When you enter a website like "" your device sends a query to a DNS server to find its corresponding IP. There are many DNS providers, with Cloudflare, Google, and OpenDNS being the most common. You can check which IPs to add for each provider and include their IPv6 versions as well. You might assign both primary and backup lookup roles to the same service—for example, using 8.8.8.8 and 8.8.4.4 for Google, or alternatively 1.1.1.1 for Cloudflare with 8.8.8.8 as a backup. This setup ensures continuity if the main server fails, which is rare for large providers like Google or Cloudflare.
