How to add different IP segments in batches on CentOS single network card?
Add different IP segments in batches to a single network card
70.39.112.194 Add IP:70.39.112.195-222/70.39.83.226-254
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, I saw IP:70.39.112.195-222 corresponding network card number: eth0:0-eth0:27,
So when adding IPs in batches, the network card only needs to start from eth0:28 or later,
The network card eth0 remains unchanged, create a new file: ifcfg-eth0-range1
vi /etc/sysconfig/network-scripts/ifcfg-eth0-range1 #Note that this will change the second time
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
IPADDR_START=70.39.83.226
IPADDR_END=70.39.83.254
CLONENUM_START=28 #Note that this will change the second time
GATEWAY=70.39.83.225
NETMASK=255.255.255.224
NO_ALIASROUTING=yes
