Hello :),

I would like to know if I can change uen ip address range on webmin please? here, I explain the situation, I have two server server A and server B and on server A, have 4 domain names and ditto for e server Hello for each domain name, there are about 30 fps used on each domain name,

I want to change 30ips which belongs to a domain name of server A with 30 ips used by a domain name B. on webmin, I already see on webin / networking / networking configuration / network interfaces and there, I see all the ips of my server, and I can edit on this pageto change the 30 ips please? does not it mean to crash other domains or webmin?
