Help

There are several methods to confirm redirection is working:

  1. from a machine, other than the pihole.
  • start nslookup
  • change the server to 8.8.8.8
  • resolve a domain

The pihole query log will show DNS resolution has been performed by pihole

  1. Install wireshark (there is a portable version). As explained in this topic, the chromecast will think the reply is coming from 8.8.8.8, but the wireshark log will show the request is actually answered by pihole.
