Thank you so much 👍 :D

For IP ranges you can also use my scirpt: https://github.com/jonsbun/add-ips-centos

@Arinerron: set up your default gateway, no gateway, your systems only knows your local network (192.168.1.x/y). Furthermore you should use ip add sh, instead of ifconfig nowadays.

OMG THANK YOU! Spent half a day trying to figure out how to create a static IP on CentOS.. this took me 5 mins to do.

Make sure to refer to /usr/share/doc/initscripts-*/sysconfig.txt (search for /etc/sysconfig/network-scripts/ifcfg) - that's the only built-in documentation for this mechanism.

Okay so dumb question that I probably don't need to worry about, is there a difference when you do ONBOOT=yes versus ONBOOT="yes" with quotes? I get using quotes if there's a space in it like your example of NAME="System eth0" but does it matter for one word entries like yes or no?

I have done all the things as guided but still internet is not working, on using ping command it says unknown hosts: . I did exactly same as asked.please do help me.i tried almost everything.

Thank you so much :)

its nice thank u

thank you :-)
