Filterable The name of this Record. For requests, this property's actual usage and whether it is required depends on the type of record this represents:

A and AAAA: The hostname or FQDN of the Record.

NS: The subdomain, if any, to use with the Domain of the Record. Wildcard NS records (*) are not supported.

MX: The mail subdomain. For example, sub for the address user@sub.example.com under the example.com Domain.

• The left-most subdomain component may be an asterisk (*) to designate a wildcard subdomain.
• Other subdomain components must only contain letters, digits, and hyphens, start with a letter, end with a letter or digit, and contain less than 64 characters.
• Must be an empty string ("") for a Null MX Record.

CNAME: The hostname. Must be unique. Required.

TXT: The hostname.

SRV: Unused. Use the service property to set the service name for this record.

CAA: The subdomain. Omit or enter an empty string ("") to apply to the entire Domain.

PTR: See our guide on how to Configure Your Linode for Reverse DNS
(rDNS).

Filterable The target for this Record. For requests, this property's actual usage and whether it is required depends on the type of record this represents:

A and AAAA: The IP address. Use [remote_addr] to submit the IPv4 address of the request. Required.

NS: The name server. Must be a valid domain. Required.

MX: The mail server. Must be a valid domain unless creating a Null MX Record. Required.

• Must have less than 254 total characters.
• The left-most domain component may be an asterisk (*) to designate a wildcard domain.
• Other domain components must only contain letters, digits, and hyphens, start with a letter, end with a letter or digit, and contain less than 64 characters.
• To create a Null MX Record, first remove any additional MX records, then create an MX record with empty strings ("") for the target and name. If a Domain has a Null MX record, new MX records cannot be created.

CNAME: The alias. Must be a valid domain. Required.

TXT: The value. Required.

SRV: The target domain or subdomain. If a subdomain is entered, it is automatically used with the Domain.
To configure for a different domain, enter a valid FQDN. For example, the value www with a Domain for
example.com results in a target set to www.example.com, whereas the value sample.com results in a
target set to sample.com. Required.

CAA: The value. For issue or issuewild tags, the domain of your certificate issuer. For the iodef
tag, a contact or submission URL (domain, http, https, or mailto). Requirements depend on the tag for this record:

• issue: The domain of your certificate issuer. Must include a valid domain. May include additional parameters separated with semicolons (;), for example: www.example.com; foo=bar
• issuewild: The domain of your wildcard certificate issuer. Must be a valid domain and must not start with an asterisk (*).
• iodef: Must be either (1) a valid domain, (2) a valid domain prepended with http:// or https://, or (3) a valid email address prepended with mailto:.

PTR: Required. See our guide on how to Configure Your Linode for Reverse DNS
(rDNS).

With the exception of A, AAAA, and CAA records, this field accepts a trailing period.

Filterable The type of Record this is in the DNS system. For example, A records associate a domain name with an IPv4 address, and AAAA records associate a domain name with an IPv6 address. For more information, see the guides on DNS Record Types.
