Additional DNS CLI configuration
Further options are available from the CLI with the command config system dns. Within this command you can set the following commands:
• dns-cache-limit - enables you to set how many DNS entries are stored in the cache. Entries that remain in the cache provide a quicker response to requests than going out to the Internet to get the same information.
• dns-cache-ttl - enables you to set how long entries remain in the cache in seconds, between 60 and 86,400 (24 hours).
• cache-notfound-responses - when enabled, any DNS requests that are returned with NOTFOUND can be stored in the cache.
• source-ip - enables you to define a dedicated IP address for communications with the DNS server.
