"host" seems to return the right IPs, but:

"wget" is resolving it to the wrong IP... (???)

Do you have something strange in /etc/hosts?

What is your /etc/resolv.conf like?

Can you try to use "curl" instead of "wget" to see if it resolves right?

Also, use "curl -v http://..." to see to which IP you are connecting.

As the problem is in domain names, I would say it's either /etc/hosts
or a DNS cache, so sniffing the network won't probably give you many
clues... Does your Windows machine use different resolvers than your
Linux machine?

HTH,
