Is it possible to have two differnt sites with the same URL?

Bountiful Wi-Fi just got a call from someone saying that there's a company in China that's using the "www.bountifulwifi.com" URL. Is that possible? Most would think not, but then the questions was post on LinkedIn to see if anyone knew anything about this subject. The answers received were not expected; apparently, it IS possible.

This was the best response:

"The mapping between IP address and the URL is defined by the DNS system and ultimately the 13 root servers. To mess with a domain you would have to compromise the DNS system. This could be done at a lower level if you had control of a DNS server below the root level. However, the interference would not be obvious to everyone on the Internet, only those relying on that lower level DNS server.

"My advice to you if you are worried would be to track down the person making the claim and have them take screen shots. Then try to find another person in a similar location (e.g. on the same network or using the same ISP). If you start to gather real evidence of a problem, expand your investigation. If you can't get evidence, write it off as nonsense."

There were two other answers that added to the first, and they were as follows:

"As suggested, China compromises the global DNS method by forcing the entire country to make use of a secondary authoritative DNS, that filters out all the stuff they don't want their inhabitants to see. As such all of China will not be able to see what is going on in Tibet. Remember the Google issue?

"For those that don't know about it: Google would be stopped from their activities in China if they would not block all news about the Chinese occupation of Tibet to Chinese Internet users. The Chinese government would just redirect all Google URLs to another site. For a while, the entire world would not get any search on Tibet returned by Google.

"So yes, who controls the main DNS system in China can delegate any domain again, even though it has already been registered for the rest of the world. Face it, your machines must be evil!!! :-)"

"...if your URL is routing to another company in China it's not due to Google (implied by the evil comment) but the Chinese government.

"DNS (Domain Name Service) is what translates human-readable names (e.g. 'www.microsoft.com') into the binary IP addresses that are actually used to move data packets around on the Internet. All China has done is to re-route traffic looking for bountifulwifi.com to a different IP address, and it likely only cost a small bribe."

802.11n is on the move...

Well, maybe not, but consumers are acting like the standard is already ratified, while many IT professionals are waiting it out. A recent webinar did a poll about 802.11n technology and integration into current networks; 75% of the respondents (they were mostly IT professionals) said they would wait until the standard's ratification before they would change network backbones.

The promise of 300 Mbps makes business people salivate, but they're not thinking of what people will do with the extra bandwidth. There's a sneaking suspicion that people will be using it to download music and movie files while doing their work. Systems are going to be just as bogged down as they are now, but it won't be people just doing their work; it'll be people doing more non-work related things WHILE they work.

Maybe it can be stopped with software, but we'll see how long it takes for people to work their
way around those programs. It might take WEEKS to find a fix, if bosses are lucky.

It's hard to see the huge advantage to BUSINESSES for installing 802.11n at this point!
