If that's not a system on your local network, then it appears that
someone's spoofing local IPs to try connecting to your system.
196.168.*.* should be nonrouteable.  A firewall will block these
connections.

Be default, X11 doesn't allow TCP/IP (remote) connections in more recent
versions, though this can be overridden.

Peace.
