Address handling of contacts is not an easy task as it requires quite up and down from the SERVER. It requires the data to be TRANSFERRED from server to client and this is simple. The data that is sent to client is overwritten or if it is not already created then it gets created at that TIME. The TRANSACTION from client to server is complex procedure as the contacts that are being given from client to the server requires ample amount of time and it requires the server to accept the messages from the client as well. This requires the server to be having the information regarding the client location and the services through which the TRANSFER of the addresses are happening.

• To handle the addresses for contact, the client makes a request and the server responds to it. 
• Server then searches its repository and tries to find out regarding the client’s request.
• If found successfully the result is returned to client, if not then error message is sent to the client regarding his request.
