Stucked with assigning additional ip blocks to opennebula kvm centos 7

Hello guys,

I just bought a server with following ip assignments when i ask my provider for additional ip configuration help they gave me the link to this tutorial https://www.unixmen.com/linux-basics-assign-multiple-ip-addresses-single-network-interface-card-centos-7/ as it was for multiple addresses in the same subnet I just google more and found this tutorial https://zubayr.github.io/virtual-ip-assignment/ and i did exactly as it say by creating 2 range file for each of the following assignments but it didn't work.

IPv4 Assignment #1: xy3.208.x53.242/29
IPv4 Assignment #2: y4.9x.25.xx2/28

I can successfully configure the server with only one ip block with bridged networking but i need to know how to configure it with the additional ip block.

I really appreciate if you guys can provide me with a solution as soon as possible.

Thank you.

    paste your interface configs (including bridge) and perhaps we can see what the issue is?

  • cubedatacubedata Member, Patron Provider

    so you are trying to configure the server with both the /29 and /28?
    because if you want to do that; we all would need to see how the server is configured(interface,bridges,etc) to know what you are doing wrong.

    IPv4 Assignment #1: 173.208.172.250/29
    IPv4 Assignment #2: 173.208.201.224/28

  • MrJMrJ Member

    I didn't receive the gateway info and other things for IPv4 Assignment #2: 173.208.201.224/28 from my provider

  • WSSWSS Member

    It's a /28, so you lose 2 of the 16 if it's assigned normally (netmask 255.255.255.240). Hope that helps, because without knowing if they sent it as /32s..

  • AnthonySmithAnthonySmith Member, Patron Provider

    what, you have 3 bridges configured, 1 of them is randomly configured as type "Ethernet", the main bridge interface holds no HW address or IP's.

    Sorry mate, that's a complete mess.

    Start again.
