The records you can set

A, CNAME and TXT records, the values each accepts, and the rules the zone enforces.

The editor under Domains holds every record for your name. Three types are supported, and each one is checked when you save it rather than when somebody queries it.

The name field#

A record's name is the label under your domain. @ means the domain itself, which DNS calls the apex; anything else is a subdomain of it.

Name	Answers for
`@`	`yourname.ce`
`www`	`www.yourname.ce`
`api.dev`	`api.dev.yourname.ce`

A#

An A record points a name at an IPv4 address.

The address has to be routable on the public internet. Loopback, private, link-local, multicast and broadcast addresses are refused, because a record pointing at one of them only ever sends the person querying it back to their own network.

CNAME#

A CNAME points a name at another hostname, and the resolver follows it from there.

Two rules come with it, and both are DNS rules rather than CEagle ones:

A CNAME cannot sit at the apex. Use an A record at @.
A CNAME cannot share a name with any other record. If www is a CNAME, www cannot also be an A or a TXT.

TXT#

A TXT record carries up to 255 printable ASCII characters. It is what verification challenges and policy records like SPF use.

TTL#

Every record carries a TTL: how long a resolver may cache the answer, in seconds. The console shows the range the zone accepts and fills in a default. Lower it before a change you want to take effect quickly, and raise it again once the address has settled.

Limits#

A domain holds a fixed number of records, shown on the editor. An identical record — same name, same type, same value — is refused rather than duplicated.
