CallerIP shows connections to your system in real-time, including the
connection time, remote and local IP address, country of origin, remote and
local ports being accessed. For Windows XP systems, the process ID is also
identified, which helps you determine if the process is legitimate. A simple
click on an IP address shows you where the connection originates on a global map
along with domain and network registration information. CallerIP scans all the
ports on your system and alerts you to any backdoors, HTTP Web, FTP, or SMTP
servers running, which could provide unauthorized access.
