Question 1

What is a DNS lookup?

Accepted Answer

A DNS lookup queries the Domain Name System to retrieve DNS records for a domain. It translates human-readable domain names into machine-readable information such as IP addresses, mail servers, and more.

Question 2

Which DNS record types does PixDNS support?

Accepted Answer

PixDNS supports A, AAAA, MX, TXT, NS, CNAME, SOA, CAA, SRV, and PTR records, plus email security analysis (SPF, DMARC, DKIM).

Question 3

Which DNS resolvers can I use?

Accepted Answer

You can query using Google DNS (8.8.8.8), Cloudflare (1.1.1.1), Quad9 (9.9.9.9), OpenDNS (208.67.222.222), or any custom DNS resolver IP address.

Question 4

How often are DNS results cached?

Accepted Answer

Results are cached in Redis with per-type TTLs: A/AAAA/PTR records for 60 seconds, MX/TXT/SRV for 180 seconds, and NS/SOA/CAA for 300 seconds. You can bypass the cache using the refresh button.

Question 5

What is the difference between A and AAAA records?

Accepted Answer

An A record maps a domain to an IPv4 address (e.g. 93.184.216.34). An AAAA record maps a domain to an IPv6 address (e.g. 2606:2800:220:1:248:1893:25c8:1946). AAAA records support the newer 128-bit IPv6 address space.

Question 6

What is an MX record?

Accepted Answer

An MX (Mail Exchange) record specifies the mail servers responsible for accepting email on behalf of a domain. Each MX record has a priority value — lower numbers indicate higher priority.
