This article shows you how to add different IP segments to the CentOS single network card, which is concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Add different IP segments to a single network card in batch

70.39.112.194 add IP:70.39.112.195-222Universe 70.39.83.226-254

Vi / etc/sysconfig/network-scripts/ifcfg-eth0-range0

DEVICE=eth0

ONBOOT=yes

BOOTPROTO=static

IPADDR_START=70.39.112.195

IPADDR_END=70.39.112.222

CLONENUM_START=0

GATEWAY=70.39.112.193

NETMASK=255.255.255.224

NO_ALIASROUTING=yes

Service network restart

After ifconfig, you can see IP:70.39.112.195-222corresponding to the network card number: eth0:0-eth0:27

So add IP in batches, and the network card will start after eth0:28.

The network card eth0 remains unchanged. Create a new file: ifcfg-eth0-range1

+

Vi / etc/sysconfig/network-scripts/ifcfg-eth0-range1 # pay attention to this second change

DEVICE=eth0

ONBOOT=yes

BOOTPROTO=static

IPADDR_START=70.39.83.226

IPADDR_END=70.39.83.254

CLONENUM_START=28 # pay attention to the second change

GATEWAY=70.39.83.225

NETMASK=255.255.255.224

NO_ALIASROUTING=yes
