Your own installed CIDR tables

When setting up networking, one of useful tool is the cidr tables, where you can refer the netmask and you can determine the cidr length for your netmask. Usually people will search the internet for network calculator or try to search for the cidr table. There is another easy way for you to have a cidr table installed in your computer and you can refer to it anytime you want using a single command. The package is perl-Net-IP. Install it using yum.

# yum install perl-Net-IP

After the installation finished, you can refer to the cidr table using the below command:

# iptab

There you go, a cidr table installed in your own computer for your own reference anytime. Have fun :-)
