How to detect IP address change or host name change
Assigning an illegal IP address to one computer by accident or by design
will probably cause IP conflicts and render computers unusable for network
operations. Network administrators would not want to see this. Then how to
efficiently detect IP changes and correct such things in time?
First you should get one computers list containing accurate IP addresses and
computer names by importing or by scanning
network. Load these data with LanHelper and from the menu bar click
"Tools > Refresh Status > Refresh By Name". On refreshing
finishing, the IP-changed computers are identified as "@!" in the Status
column. Then network administrators can locate these computers according to
other network information and correct the changes manually. To detect host
name changing based on IP address, use Refresh By IP function
LanHelper provides monitor mode for detecting IP-changed computers
periodically. Monitor mode automate the change detection, and send
notifications to network administrator if necessary, and event try to turn
on or shutdown concerned computers.
