Type: null or ((list of string) or string convertible to it)

Default: null

Example: "9.9.9.9"

zones.<name>.<name>.a.ttl

The time to live (TTL) is a field on DNS records that tells you how long the record is valid (in seconds) and thus when it will be updated.

Type: signed integer

Default: Automatically use the same ttl as the matching base domain

Example: 86400

zones.<name>.<name>.aaaa.data

Commonly used to map a name to a list of IPv6 addresses.

Default: null

Example: "2620:fe::fe"

zones.<name>.<name>.aaaa.ttl

The time to live (TTL) is a field on DNS records that tells you how long the record is valid (in seconds) and thus when it will be updated.

Type: signed integer

Default: Automatically use the same ttl as the matching base domain

Example: 86400

zones.<name>.<name>.alias.data

Maps one domain name to another and uses the dns resolver of your dns server for responses.

Type: null or string or list of string

Default: null

Example: "foo.example.com"

zones.<name>.<name>.alias.ttl

The time to live (TTL) is a field on DNS records that tells you how long the record is valid (in seconds) and thus when it will be updated.

Default: null

zones.<name>.<name>.caa.ttl

The time to live (TTL) is a field on DNS records that tells you how long the record is valid (in seconds) and thus when it will be updated.

Type: signed integer

Default: Automatically use the same ttl as the matching base domain

Example: 86400

zones.<name>.<name>.cname.data

Same as alias but the requesting party will have to resolve the response which can lead to more latency.

Type: null or string

Default: null

Example: "foo.example.com"

zones.<name>.<name>.cname.ttl

The time to live (TTL) is a field on DNS records that tells you how long the record is valid (in seconds) and thus when it will be updated.

Type: signed integer

Default: Automatically use the same ttl as the matching base domain

Example: 86400

zones.<name>.<name>.dname.data

Same as cname but also gets applied to any subdomain of the given domain

Type: null or string

Default: null

Example: "foo.example.com"

zones.<name>.<name>.dname.ttl

The time to live (TTL) is a field on DNS records that tells you how long the record is valid (in seconds) and thus when it will be updated.

Type: signed integer

Default: Automatically use the same ttl as the matching base domain

Example: 86400

zones.<name>.<name>.mx.data

List of mail exchange servers that accept email for this domain.

Type: null or (submodule) or list of (null or (submodule))

Default: null

zones.<name>.<name>.mx.ttl

The time to live (TTL) is a field on DNS records that tells you how long the record is valid (in seconds) and thus when it will be updated.

Type: signed integer

Default: Automatically use the same ttl as the matching base domain

Example: 86400

zones.<name>.<name>.ns.data

Nameserver responsible for your zone. Note, that this option technically allows for only one name server but I would strongly advise against that.

Type: null or ((list of string) or string convertible to it)

Default: null

Example:

[
  "ns1.example.com"
  "ns2.example.com"
  "ns3.example.com"
]

zones.<name>.<name>.ns.ttl

The time to live (TTL) is a field on DNS records that tells you how long the record is valid (in seconds) and thus when it will be updated.

Type: signed integer

Default: Automatically use the same ttl as the matching base domain

Example: 86400

zones.<name>.<name>.soa.data

Specifies authoritative information about a DNS zone.

Type: null or (submodule)

Default: null

zones.<name>.<name>.soa.data.expire

If a secondary server does not get a response from the primary server for this amount of time, it should stop responding to queries for the zone.

Type: signed integer

Example: ""

zones.<name>.<name>.soa.data.mname

This is the name of the primary nameserver for the zone. Secondary servers that maintain duplicates of the zone’s DNS records receive updates to the zone from this primary server.

Type: string

Example: "ns.example.com"

zones.<name>.<name>.soa.data.refresh

The length of time secondary servers should wait before asking primary servers for the SOA record to see if it has been updated.

Type: signed integer

Example: 86400

zones.<name>.<name>.soa.data.retry

The length of time a server should wait for asking an unresponsive primary nameserver for an update again.

Type: signed integer

Example: ""

zones.<name>.<name>.soa.data.rname

Email of zone administrators.

Type: string

Example: "noc@example.com"

zones.<name>.<name>.soa.data.serial

A zone serial number is a version number for the SOA record (the higher the newer). When the serial number changes in a zone file, this alerts secondary nameservers that they should update their copies of the zone file via a zone transfer. Usually most dns-utilities working with zonefiles increment it automatically.

Type: signed integer

Example: ""

zones.<name>.<name>.soa.data.ttl

Type: signed integer

Default: cfg.defaultTTL

Example: ""

zones.<name>.<name>.soa.ttl

The time to live (TTL) is a field on DNS records that tells you how long the record is valid (in seconds) and thus when it will be updated.

Type: signed integer

Default: Automatically use the same ttl as the matching base domain

Example: 86400

zones.<name>.<name>.spf

Type: submodule

Default: { }

zones.<name>.<name>.spf.data
