(There does appear to be a DNS registration problem independent of your computer. A dotted decimal IP address found from a lookup of a URI should not result in a different site being found when it is used.)

Post what you see, what operating system you are using, and what firewall you are using (software (e.g. Zonealarm) and/or hardware (e.g. wireless router)), and let's see if we can't figure this out.
