I tried to change it in the host files with the same results. Next I will
block that IP in my firewall and see what happens.

Think load-balancing, dynaminc content distribution hosting, etc.

Ahhhh...

So, the exception is not that the IP is hard-coded, but that the DNS 
resolver skips looking in hosts for that _domain_ and necessarily does 
a network DNS lookup...
