How to change the IP address of Plesk server?
- Connect to the server using SSH.
 - Generate a mapping file with current Plesk IP addresses by running the command:
# plesk bin reconfigurator /root/ip_map_file_name
 - Edit the file "/root/ip_map_file_name", for example, to change IP address 192.0.2.2 to 192.0.3.3:
Before edit:
eth0 192.0.2.2 255.255.255.0
After edit:
eth0 192.0.3.3 255.255.255.0
 - Reconfigure Plesk and its services by running the command again:
# plesk bin reconfigurator /root/ip_map_file_name
