Is this yours / do you know how this works? The responses seem pretty good, although one of the three recommended for me is giving invalid data for google.com, and it's giving me the same three servers for several different connections in the USA, some very distant from others.

I have my reservations about blindly using DNS servers without verifying their ownership and control. Consider entering "www.wellsfargo.com" into a browser. If a bogus DNS server returned a hacker's server, it could redirect you to wellsfargo.wildcard-cert-based-attacker.com. The people here might figure out that something is awry, but I think we all know people that would not catch it. Of course this is possible in theory even without the DNS server operator being malicious, but it's considerably more difficult.

Given than one of the IP addresses I was given reverse-resolved to "adsl-69-111-95-106.dsl.chic01.pacbell.net", which I assume is a consumer DSL service in Chicago, I think you're right to have reservations.

EDIT: I got the same three IP address from a host in the continental USA, and from a host in Australia; I imagine it's just serving the same three hosts to everybody. Be afraid. Be very afraid.

I got the same three, I think:

  204.74.97.104    rdns3pxpa.ultradns.net
  209.213.196.218  eth0.sfo001dn01.yipes.com
  69.111.95.106    adsl-69-111-95-106.dsl.chic01.pacbell.net
Definitely something weird going on. I'm located in The Netherlands.

Same here -- I am using an IP in the Philippines:

204.74.97.104 209.213.196.218 69.111.95.106

Same here. From Indian IP.

Something very fishy. Probably will redirect some X% of the DNS queries to spam/phishing sites ?

I got the same three as well. Those three are not in the list below either.

OpenDNS.org is a great service and is blindingly fast for me. It's also easy to remember 4.2.2.(1-4). Great for when you are out in public wifi and don't want to use some untrusted DNS server that is serving a bunch of clients from an overworked router.
