Hi my 2cents: have 2 monitoring modes
1st mode: as is track and monitor IP addresses <img src="/forums/images/graemlins/smile.gif" alt="" /> PingPlotter is still my favorite graphical tool for this
2nd mode: track FQDN names including dyndns ones
* easy to grab: either fixed IPs (FQDN only resolved ones) or FQDN (dynamic IPs)
* maybe compare tracking address with 'well-known' dyndns providers and ask at monitoring start for 'symbolic names' aka dyndns tracking mode
* present and store results under IP (mode 1) or FQDN (mode 2)
* start search for update if IP address no longer reachable, IP address change happened,
* add to route changes IP address updates
Would be great to use PingPlotter for such a monitoring.
