[Cialug] Quad9 DNS Service

[jim kraai]

I'm not an expert on these matters, so I had to find, read, and compare
lists of features

Quad9
Aggregates multiple threat databases
No requester IP address logging
EDNS requester IP address leakage prevented
Free for all users

Google DNS
No claims about blocking addresses in threat databases, internal or
external
Requester IP address will be deleted after 24–48 hours, but ISP and
location information are stored permanently
EDNS requester IP address leakage not prevented
? Free for all users

OpenDNS
Threat databases, yes
Logging of requester data is an integral feature
EDNS requester IP address leakage not prevented
Not free for business use

Different goals, different tools

I'm pretty sure OpenDNS does this sort of thing already. I think
Google DNS does too? Not that competition isn't good ;)
