What is happening is that your ISPs DNS server is redirecting your DNS query.
You can probably fix the problem with using a different DNS server as specified
To test, try
You should get
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, ...
and not an ip address.
Two issues though. If you are using DHCP, you need to make sure that
/etc/resolv.conf is not overwritten every time you boot up by the dhcp client.
Also, I don't know of a public DNS server that would accommodate anyone. Others
may have a good suggestion. You have to trust the DNS server because if it
gives you the wrong ip address for a site, that would be pretty hard to
distinguish and the odds of successful phishing would go up quite a bit.
