Help with Internet Re-directing

[sonic-fast-fingers]

My friend who lives in California was trying to use Yahoo.com's search engine. As he is trying to search something a lot of rapid scenarios happen. He clicks search and then it deviates in several different ways. After he clicks on one of the results one of the scenarios that occur is that an IP address quickly pops up in the tab bar. He took a screen shot of what he likes to call "mid-****ing me over." He was able to screen shot the IP address. He went to an IP finder and comes to find out that the IP address is located in Las Vegas, NV. (He was able to find where the IP was located because the IP finder gave him the latitude and longitude which he was able to enter in Google Earth).

The question is: Has this happened to anyone else? Is a single person purposefully messing with my friend or is this an arbitrary attack? Does the IP have any significance? How do you resolve this problem?
