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

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:

), 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 (*
