Hello,

 

I'm a little bit confused about the DNS server that resides in 2 different places. For once you can set a DNS address where you setup your internet connection.

On another hand you can setup the a primary and secondary dns address in the dhcp server settings. If I leave these blank the devices will see the dns address as the address of the router.

 

Could someone please explain what is the difference between these 2 settings and how is best to set things up?

 

Thanks a lot,

George

The internet connection DNS'es are mandatory for your router to have internet connection (TP-Link cloud connection, updating its FW, time settings, etc.)

If you omit the DHCP DNS'es, the router will use these internet connection DNS'es for all its DHCP client devices - devices use router's LAN IP address as a DNS.

If (for some reason, like a PI-Hole or other internal DNS server) you want your DHCP client devices to have different DNS'es then you can set these DHCP DNS'es different than internet connection DNS'es.

In this case your DHCP client devices will have these DNS'es - not the router LAN IP address.

If this was helpful click once on the arrow pointing upward. If this solves your issue, click once the star to mark it as a "Recommended Solution".
