Guys DC sent a message they are changing IP providers, so need to change the IP's on my 2 ispconfig servers. What is the procedure to follow to change server IP on ISPconfig (still on 3.1.15 & 3.1.15p3) ? From what I recall, all sites use the server IP, so to be sure from where in admin panel or from CLI would show what IP's are being used in server also for sites so I dont miss something site maybe using some unique IP? What a pain when DC makes such changes. Thanks.
