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
