Networking - DNS - Unbound - Local Data

Local data, which can override A / AAAA addresses, can be configured to reply to DNS queries.

The format for local-data is:

local-data: "<resource record string>"

NOTE:

The query has to match exactly unless you configure a local-zone as redirect.
If not matched exactly, the local-zone type determines further processing.
If local-data is configured that is not a subdomain of a local-zone, a transparent local-zone is configured.
For record types such as TXT, use single quotes, as in
```
local-data: 'example. TXT "text"'.
```

NOTE: local-data is often associated with a local-zone

local-zone: <zone> <type>
local-data: "<resource record string>"

If you configure local-data without specifying local-zone, by default a transparent local-zone is created for the data.

Examples

Type	Example	Comment
CNAME	local-data: “alias 3600 IN CNAME host.example.org.”	Only 1 CNAME per name, otherwise the client will not be able to resolve it (does not allow multiple entries like an A)
MX	local-data: “my.localdomain. MX 10 mail.example.org.”	“@” Is not acceptable for unbound - replace the domain's FQDN instead. Unbound does not use the default domain in this specific case.
SRV	local-data: “_sip._tcp 60 IN SRV 0 5 5060 pbx.example.org.”
