System DNS

This section describes configuring DNS on the system, namely:

  • DNS name servers
  • Domain search order

DNS name servers

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:

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

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.

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.

Example

The system is configured to attempt domain completion in the following order: vyos.io (first), vyos.net (second) and vyos.network (last):

set system domain-search domain vyos.io
set system domain-search domain vyos.net
set system domain-search domain vyos.network
