Good sites for finding IP, DNS, and adblock formatted lists
for IP blocklists take a look at FireHOL. They keep a list of all known/popular IP blocklists out there and monitor their age, number of IP's, if they're well-maintained, as well as list overlap (352 blocklists at the time of this post.)
Personally, I simply use their merged lists which combine your spamhaus, tors, dshields, emerging threats, and the like. Either way, you'll find about 99% of the lists people always talk about.
DNS and adblock lists
https://filterlists.com (mixed together unfortunately) 298 lists on this site
Personally, in the least I use Steven Black's hosts file minimally for DNS blocking since he merges about 20 or so actively-maintained DNS lists and is well-curated.
I also monitor DNS logs myself because no list out there is entirely geared towards mobile ads and analytics companies- even if they say they try to.
Thanks for the suggestion. I tried these out, but the level1 list blocks 192.168.0.0/16, which prevents local traffic.
Edit: God, and the webserver one blocked 22.214.171.124, which is Google DNS…
