Abstract

The invention relates to a method for provision of an address of an online computer, connected to a data network, for at least one receiving computer. The aim of the invention is the provision of an address, in particular, a temporary IP address in which known disadvantages do not occur. Said aim is achieved, whereby the online computer carries out the following steps: transmission of a first data set, with the identification for at least one server structure globally accessible by the data network, to the receiver computer, whereby the server structure is selected from a number of available server structures, transmission of a second data set, identifying at least one code designator, to the receiving computer and storage of the address of the online computer together with the code designator on the identified server structure.

Claims

1. A method for provision of an address of an online computer which is connected to a data network, for at least one receiving computer wherein the method performed by the online computer comprises:

transmitting a first data set comprising the identification of at least one server structure globally accessible over the data network, to the receiving computer, the server structure being selected from a plurality of available server structures;

transmitting a second data set which identifies at least one codeword, to the receiving computer; and

storing said address of the online computer together with said identified codeword on the identified server structure.

2. A method according to claim 1, further comprising:

the receiving computer sending a query to the server structure, which query contains the codeword.

3. A method according to claim 2, further comprising:

the server structure sending back, as a response, the address of the online computer.

4. A method according to claim 3, further comprising:

the server structure forwarding the response to the online computer, and the online computer sending back to the receiving computer, as a response, the address of said online computer.

5. A method according to claim 1, wherein the data network is the Internet, and the address is an IP address.

6. A method according to claim 1, wherein the data network is the Internet, and the address is an address unambiguously associated with the IP address.

7. A method according to claim 6, the method further comprising:

the receiving computer determining the IP address of the online computer via a second query which contains the associated address.

8. A method according to claim 1, wherein the identification of a server structure globally accessible over the data network is the name of an IRC network.

9. A method according to claim 8, wherein the query sent by the receiving computer is a WHOIS command sent to the IRC server structure.

10. A method according to claim 1, further comprising:

assigning a time-limited validity to the identification of a server structure globally accessible over the data network.

11. A method according to claim 10, wherein the first data set comprises a plurality of identifications of server structures globally accessible over the data network, which identifications have time-limited validity, the durations of such validities covering different time intervals.

12. A method according to claim 1, further comprising:

assigning a time-limited validity to the codeword.

13. A method according to claim 12, wherein the second data set identifies a plurality of codewords having time-limited validity, the durations of such validities covering different time intervals.

14. A method according to claim 1, wherein the codeword is computed by a defined algorithm with at least one variable;

and

wherein the second data set has at least one value for the at least one variable for computing the codeword.

15. A method according to claim 1, wherein the variable has a time-limited validity.

16. A method according to claim 15, wherein the second data set has a plurality of variables which have time-limited validity, the durations of such validities covering different time intervals.

17. A method according to claim 14, wherein the algorithm for computing the codeword employs time-dependent information.

18. A method according to claim 1, wherein the codeword is a nickname for logging on to an IRC network.

19. A method according to claim 1, further comprising:

transmitting from the receiving computer to the online computer the following;

a first data set, with the identification of at least one server globally accessible over the data network, the server structure being selected from a plurality of available server structures;

a second data set, identifying at least one codeword;

the receiving computer storing on the identified server structure the address assigned to said receiving computer, together with the identified codeword.

20. A method according to claim 1, further comprising:

prior to the initial transmission of the first and second data sets, providing a request to the user of the computer to input an entry indicating approval and acknowledgment of such transmission via an input device connected to the computer.

21. A method according to claim 20, wherein the approving and acknowledging input is a command to send an electronic mail (email) message with the first and second data sets, which message is sent to a specified address.

22. A method according to claim 20, the method further comprising:

after the computer has received the aforesaid electronic message containing the first and second data sets, said computer displaying the identity of the sender of the message on a display device connected to the computer,

displaying a prompt on said display device, requesting that the user of the computer input an acknowledgment by means of an input device connected to the computer, and

sending a first and second data set back only if such an acknowledgment is input.

23. A computer readable memory medium storing program instructions, wherein the program instructions are executable to:

transmit a first data set comprising the identification of at least one server structure globally accessible over a data network, to a receiving computer, the server structure being selected from a plurality of available server structures;

transmit a second data set which identifies at least one codeword, to the receiving computer; and

store an address of an online computer together with the identified codeword on the identified server structure;

wherein the program instructions are executable to provide the address of the online computer, which is connected to the data network, to the receiving computer.
