Method and arrangement for enabling communication with a client device

An arrangement in a client device for making a currently valid communication address of the client device publicly available, which can be used for communication with the client device, comprising:

• means for sending a freely composed connectivity key to a publicly available connectivity server, wherein said connectivity key is searchable by means of web searching using a search engine, and
• means for sending connectivity parameters associated with the connectivity key to the connectivity server, said connectivity parameters including at least the communication address of the client device, which then becomes publicly available in the connectivity server by web searching of the associated connectivity key using said search engine to obtain a search result as a URL of the connectivity server, specifically pointing to a web page containing the connectivity key and associated communication address of the searched client device, wherein the communication address of the client device can be retrieved by means of said URL of the connectivity server.

A method of making a currently valid communication address of a client device publicly available, which can be used for communication with the client device, comprising the following steps, as executed in a publicly available connectivity server:

• receiving a freely composed connectivity key which is searchable by means of web searching using a search engine,
• receiving connectivity parameters associated with the connectivity key, said connectivity parameters including at least the communication address of the client device, and
• storing a connectivity record for the client device including the received connectivity key and associated connectivity parameters, thereby making the connectivity parameters publicly available by web searching of the associated connectivity key using said search engine to obtain a search result as a URL of the connectivity server, specifically pointing to a web page containing the connectivity key and associated communication address of the searched client device, wherein the communication address of the client device can be retrieved by means of said URL of the connectivity server.
