In Linux family operating system CentOS, RedHat, SuSe, Debian, Gentoo, Slackware, Ubuntu and etc. most of every operating system network configuration path is difference.

Changing IP address of an interface without rebooting or restart all network interface in Linux.

Can refresh the network connection without rebooting the system, Open the Command Prompt,

ethtool command is helpful to check the speed and change settings of network interface, also get information which works now for most network interface cards.

Everything to check information about the hardware by commands your linux system, the following commands will get network inteface, which IP address configured to specific interface like eth0, eth1, etc...

Assume that, if you are working in Data Center or running your application in VPS server, we can change static IP Address without downtime and reboot your Server.
