System DNS

##########
|
|
|
|
.. warning:: If you are configuring a VRF for management purposes, there is
|
|
currently no way to force system DNS traffic via a specific VRF.
|
|
|
|
This section describes configuring DNS on the system, namely:
|
|
|
|
* DNS name servers
|
|
* Domain search order
|
|
|
|
|
|
DNS name servers
|
|
================
|
|
|
|
.. cfgcmd:: set system name-server <address>
|
|
|
|
Use this command to specify a DNS server for the system to be used
|
|
for DNS lookups. More than one DNS server can be added, configuring
|
|
one at a time. Both IPv4 and IPv6 addresses are supported.
|
|
|
|
|
|
|
|
Example
|
|
-------
|
|
|
|
In this example, some *OpenNIC* servers are used, two IPv4 addresses
|
|
and two IPv6 addresses:
|
|
|
|
.. stop_vyoslinter
|
|
|
|
.. code-block:: none
|
|
|
|
set system name-server 176.9.37.132
|
|
set system name-server 195.10.195.195
|
|
set system name-server 2a01:4f8:161:3441::1
|
|
set system name-server 2a00:f826:8:2::195
|
|
|
|
.. start_vyoslinter
|
|
|
|
Domain search order
|
|
===================
|
|
|
|
In order for the system to use and complete unqualified host names, a
|
|
list can be defined which will be used for domain searches.
|
|
|
|
|
|
.. cfgcmd:: set system domain-search domain <domain>
|
|
|
|
Use this command to define domains, one at a time, so that the system
|
|
uses them to complete unqualified host names. Maximum: 6 entries.
|
|
|
|
|
|
.. note:: Domain names can include letters, numbers, hyphens and periods
|
|
with a maximum length of 253 characters.
|
|
|
|
.. _name-server:domain-search-order_example:
|
|
|
|
Example
|
|
-------
|
|
|
|
The system is configured to attempt domain completion in the following
|
|
order: vyos.io (first), vyos.net (second) and vyos.network (last):
|
|
|
|
|
|
.. code-block:: none
|
|
|
|
set system domain-search domain vyos.io
|
|
set system domain-search domain vyos.net
|
|
set system domain-search domain vyos.network
|
