A DNS record is a line in a domain's settings that maps the domain to a server, a mail service, or a piece of text used for verification.
DNS, the Domain Name System, turns names like pageo.me into the numeric addresses computers use. Each domain has a set of records, managed at the company where the domain is registered or hosted.
The common types each do one job. An A record points a name to an IPv4 address. A CNAME record points a name to another name. An MX record routes email. A TXT record holds text, often to prove that you own the domain.
Changes do not apply everywhere at once. Each record has a time to live (TTL) that says how long other servers may cache it, so a change can take minutes, and sometimes hours, to spread.
Example
To connect links.example.com, a creator adds a CNAME record with the host links and the value cname.pageo.me, plus a TXT record that proves they own the domain.
In pageo
The pageo custom domain dialog shows the exact records to add and checks them every few seconds until your domain connects.
