Search the common DNS record types by their short name or by keyword and read a plain explanation of what each one does. Type MX to learn about mail routing, or type a word like mail, alias or security to see every related record type. DNS is the address book of the internet, and each record type carries a different kind of information, from mapping a name to an IPv4 address with an A record to publishing email authentication policies in TXT records. Knowing which record type to use is essential when setting up a domain, pointing a site at a host, configuring email, or troubleshooting why a name does not resolve as expected. Each entry notes the typical purpose and what the record points to. The whole reference lives on the page, so it works offline and instantly, and no query you type is sent anywhere.
