Health Check Settings : Include public DNS servers


In the ‘Health check settings’ in the WAN configuration, it’s possible to check ‘Include Public Dns servers’.

Who’s are these Public DNS servers ?
When does peplink use them ? Only when defined DNS servers stop working ? All the time ??



Google DNS, OpenDNS, MIT DNS

When Peplink tries the WAN DNS server failed and hit Health Retries, public DNS servers will be used until the link recovered.
