Abstract
A connection is established on the Internet between an originating client terminal and a destination client terminal, the latter having an IP address which has been dynamically assigned by an Internet Access Service Provider (IASP) and which is unknown to the originating client terminal. Using a known e-mail address associated with a user of the destination client terminal, which e-mail address includes a name associated with the user and the domain name associated with the IASP, which both provides access to the Internet and e-mail service to the user, the IP address that IASP is determined from a Domain Name Server (DNS) on the Internet. The IASP is then queried at that address to determine whether the user with the known name is currently logged on. If that user is logged on, the IP address assigned by the IASP to the destination client terminal is provided to the originating client terminal and a connection is then established to the destination client terminal at the provided IP address.
