Pi-Hole – A black hole for Internet advertisements

I don't understand Vixie. I have a Chromecast Ultra. On my Firewall at all, I reject all requests to 8.8.8.8(and .4.4) with a ICMP unreachable. This forces the CC Ultra to use the DHCP allocated DNS Server (a pihole) which works just fine.

I don't understand why he says you have to route and answer 8.8.8.8. You really don't.

If his point is you can't override the built in DNS without some sort of FW hackery though, then yea his point stands.

Does the dest unreach solution work on the original Chromecast?

Yup, I have a CC original, 2 CC Audio and a CC Ultra. This trick works for them all

How about Roku, AppleTV, Amazon Fire whatever? (I do not know all the correct brand names but I am presuming other companies are trying to hardcode DNS servers too.)

I don't own any of those. But given those devices don't have ties to Google, I doubt they're trying to force people to use their own DNS. I don't even think Roku, Apple or Amazon run public DNS servers.

Like you, I do not have these to test, but I have read that at least Roku have been hardcoding GoogleDNS servers.
