# DNS configuration file (classic)

Sample configuration file for the Data Enricher `enricher_nxad.conf`

```
[NXDNS]
partial_refresh_enabled = True
partial_refresh_frequency = 60
 
# Enables/disables the full refresh functionality.
# When enabled this will refresh all engine destinations info at the time configured in full_refresh_time parameter.
# Attention! This can be a very heavy load job, please configure the execution time accordingly.
full_refresh_enabled = False
 
# You may configure a refresh on a daily or weekly basis.
# For a daily full refresh, enter only the local time in a 24 hour format, for example 23:30.
# For a weekly full refresh, add the desired weekday before the time, for example: Sat 23:30.
# The possible values are: Mon, Tue, Wed, Thu, Fri, Sat and Sun.
# Examples:
#   Daily full refresh at 3:17 AM
#   full_refresh_time = 3:17
#   Weekly full refresh on Fridays at 4:55 PM
#   full_refresh_time = Fri 16:55
full_refresh_time = Mon 23:30
 
# Comma separated list of DNS servers.
# Example: servers = 8.8.8.8, 8.8.4.4
servers = <server1>,<server2>
# Timeout for each DNS server in seconds
max_dns_server_timeout = 0.5
# Percentage of allowed DNS server errors, measured with respect to the total number of destinations
max_perc_dns_server_errors = 35

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.nexthink.com/platform/~/changes/Sh4xqs4GDClkDKT9Hvux/integrations/api-and-integrations-classic/data-enricher-classic/dns-configuration-file-classic.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
