Server and methods for performing synchronization and resynchronization of networking information with client devices. During standard operations, client networking data discovered by a given client device are received by the server from the given client device, stored by the server, and forwarded by the server to other client devices. Client networking data from the other client devices received and stored by the server are forwarded to the given client device. Upon occurrence of a pre-defined event at the given client device preventing exchange of information between the given client device and the server, a resynchronization of the client networking data is performed between the given client device and the server. The synchronization and resynchronization mechanisms are based on unique version numbers respectively generated by the server and the given client device.
