A system, apparatus and method of notifying a user that there may be a possibility of communicating with a computer system other than an intended one are provided. When a host in use by the user is to request a DNS name service, the request is sent to two or more DNS servers. If all the servers return the same IP address, then there is a likelihood that the user may communicate with the intended computer system. If, however, two or more different IP addresses are returned, there is a high likelihood that the user may communicate with a computer system other than the intended one. When this occurs a warning is generated notifying the user of such a likelihood.
