# 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:
```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
```
## 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\>
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):
```none
set system domain-search vyos.io
set system domain-search vyos.net
set system domain-search vyos.network
```
