security kiss shows ISP DNS but i don't use them

When i use security kiss https://ipleak.net/ shows my DNS as coming from my ISP. How can this be as I do not use my ISP DNS? In network sharing/properties i enter a DNS not conneced to my ISP

 

It's probably pushed from the router. To avoid that, you must set LAN adapter properties to static DNS. Or setup firewall rules.

 

Thanks it is the router. Fixed it

 

Or yeah, tweak the router

 

dd-wrt would work as a tweak, LOL!
