Ads not blocked in Windows 10

Hi,

I recently set up pi-hole on my raspberry pi 2 and set it as the dns on my router and in my Windows 10 ipv4 settings. Ad blocking seems fine on android devices connected to my network but my windows 10 pc does not appear to be blocking ads.

I tried this on site rajah.com which is very ad heavy. I enabled developer tools and inspected the elements containing the ads to see where they come from.

I confirmed several domains which should have been pi-holed according to the pi-hole query log but still showed up in my developer tools network tab as 200 OK -

s1.2mdn.net
s0.2mdn.net
pagead2.googlesyndication.com

I tried this in 3 different browsers (chrome, IE 11 and Edge) and also flushed my dns cache on the pc before starting.

Any suggestions?

Thanks,

Allan

Found the problem. I also needed to set the ipv6 dns server in windows
