Network access arrangement
First Claim
1. A method of operating a network access apparatus connected between at least one communications terminal and a network, said network access apparatus including a store populated with at least one network address allocated to a communications terminal, said method comprising:
- receiving a request from a communications terminal for a file stored in said network, said file request including an originating network address;
comparing said originating network address with the contents of said store;
in the event that said comparing step finds said originating network address in said store, returning a substituted file to said communications terminal in place of said requested file and deleting said originating network address from said store; and
in the event that said comparing step does not find said originating network address in said store, returning the requested file thereby avoiding continued return of a substituted file.

Abstract
A network access arrangement must allocate and store a network address to a client computer. The network access arrangement then monitors file request messages which include an originating network address and compares the originating network address in each request with the stored network address. In the event of a match then instead of returning the requested file, a substituted file is returned to the client. The originating network address is deleted from the network access store such that subsequent file requests are unaffected. Thus, instead of client computer user first receiving the default file requested, a file substituted by the operator of the network access arrangement is received. This substituted file can, for example, contain a variety of information of utility to the user, including news, service information and advertisements.

5. A method of operating a network access arrangement, said arrangement being connected between at least one client and a network;
- said method comprising;
receiving a request from a client for connection to said network; allocating a network address to said connection requesting client in response to said connection request; storing said newly allocated network address in a store of such newly allocated network addresses; receiving a request from a client for a file stored in said network;
said file request including an originating network address;comparing said originating network address with the contents of said store; in the event that said comparing step finds said originating network address in said store, returning a substituted file to said file requesting client in place of said requested file and deleting said originating network address from said store; and in the event that said comparing step does not find said originating network address in said store, returning the requested file thereby avoiding continued return of a substituted file.
