DNS record types are easy to half-remember — everyone knows A and CNAME, but the difference between SRV and CAA, or DNSKEY and DS, tends to blur together until you actually need to configure one correctly.
What Is the DNS Record Types Cheatsheet?
A searchable, filterable reference covering the common DNS record types — organized into Core, Email, Security, and Service Discovery categories — with a plain-language description and a real-world example for each.
