Centos: multiple IP addresses

I just bought 10 extra IPs from my host. How do I point these at my CentOS 5 server?

• Use IP aliasing on the host.

  ifconfig eth0:1 192.168.0.100 netmask 255.255.255.0
  ifconfig eth0:2 192.168.0.101 netmask 255.255.255.0
  

  To do it permanently you will have to use the files in /etc/sysconfig/network-scripts/ifcfg-<interface>

  And so on. But why do you need multiple IPs for a single host? SSL/TLS?

• On CentOS you can use a ifcfg-eth?-range? file to assign multiple IP adresses. For example; you want to assign additional IP adresses to your eth0 interface and you don't have any additional addresses assigned yet. Create the file /etc/sysconfig/network-scripts/ifcfg-eth0-range0:

  IPADDR_START=10.0.0.10
  IPADDR_END=10.0.0.19
  CLONENUM_START=0
  

  When you already have assigned additional IP addresses the CLONENUM_START value should match the next available eth0:x number.

  If the IP addresses aren't in order you have to create an ifcfg-eth0:x file for each of the addresses. The content should look like this:

  DEVICE=eth0:0
  IPADDR=10.0.0.10
  NETMASK=255.255.255.0
  ONBOOT=yes
  

  Change the DEVICE value to the corresponding filename and run ifup eth0:0 to bring the interface online.
