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
