People find it rather hard to add the IPs manually on a Plain server. Following are the steps you can follow to add a range of IPs on a CentOS server:<\/p>\n

1 )<\/strong> Change directory to \/etc\/sysconfig\/network-scripts\/ using the ‘cd’ command:<\/p>\n

cd \/etc\/sysconfig\/network-scripts\/<\/strong><\/span> (this directory contains Interface configuration files)<\/p><\/blockquote>\n

2)<\/strong> Create a file ifcfg-eth0-range0 using your favorite text editor like ‘pico’<\/p>\n

pico ifcfg-eth0-range0<\/span><\/strong><\/p><\/blockquote>\n

3)<\/strong> Add the following lines to the file:<\/p>\n

IPADDR_START=1.1.1.10
\nIPADDR_END=1.1.1.20
\nCLONENUM_START=1<\/strong><\/span><\/p><\/blockquote>\n

where,<\/strong><\/p>\n

IPADDR_START is the first IP in the range.
\nIPADDR_END is the last IP in the range.
\nCLONENUM_START=1, where 1 will start adding IPs from eth0:1<\/strong><\/p><\/blockquote>\n

4)<\/strong> Save and exit the file<\/strong>.<\/p>\n

5)<\/strong> You now need to execute “ifup-aliases” script for the range of IPs to take affect. Execute the following command:<\/p>\n

.\/ifup-aliases eth0<\/strong><\/span><\/p><\/blockquote>\n

This will add the IPs on eth0 and will bring all the virtual interfaces up. You can view all the interfaces using the “ifconfig<\/strong><\/span>” command.<\/p>\n","protected":false},"excerpt":{"rendered":"
