assign server a public static IP

assign a server a public static IP How do you assign a server a public IP?? I am running a modem in bridge mode to my server I edit file /etc/sysconfig/network-scripts/ifcfg-eth0 <looks like this > # DEVICE=eth0 # BOOTPROTO=static # HWADDR=12:23:44:43:56:43 # IPADDR=[login to view URL] < [login to view URL] is my public ip > Once its changed I get no connection I can't ssh into it. --------------- Description - Plain and simple.. let me know which files it is I have to edit. Where to put in the info my isp gave me.. I then edit them,Then if it works you get paid... We can communicate through email or messenger.
