Unbound is a validating, recursive, and caching DNS resolver that supports DNSSEC.

Install

Install the package:

apk add unbound

Configure

The following configuration is an example of a caching name server (in a production server, it's recommended to adjust the access-control parameter to limit to your network).

  • /etc/unbound/unbound.conf
server:
        verbosity: 1
        interface: 10.0.0.1
        do-ip4: yes
        do-ip6: no
        do-udp: yes
        do-tcp: yes
        do-daemonize: yes
        access-control: 0.0.0.0/0 allow
python:
remote-control:
        control-enable: no

Set auto-start, start and test the daemon

Set to auto-start then start unbound:

rc-update add unbound /etc/init.d/unbound start

Test:

dig nl.alpinelinux.org @10.0.0.1
