Additional IP addresses / CentOS - Solved Please close

edited March 2014 in Help

We have just bought a dedicated server off Delimiter and we also purchased 4 extra IP's.
My question is how do we point the extra IP's to our new server? The IP's just time out. We used a dedicated server last year and installed SolusVM and that seemed to pick up our extra IP's automatically. We did ask for a cancel of the extra IP's but have had no reply, we have paid for them for 3 months so I guess we would try again. This is a collage project and we would appreciate any help from the community. We have posted this in the help category of this site, please note that we are leaning and can do without rude or sarcastic comments.

  • Add the IP addresses to your VLAN.

    You most likely need to add the i addresses to your server.

    Look at the file /etc/networking/interfaces.

    Presuming a standard setup (BE SURE TO CHECK!!).

    add something like:

    auto eth0:0
    iface eth0:0 inet static
    address 1.2.3.4
    netmask $NETMASK
    gateway $GATEWAY
    

    eth0 may be em0 (if you are using the new naming scheme).

    There are other ways to do this (this is actually a slightly outdated way).

    Ask your host for the values of $NETMASK and $GATWAY, or you may be able to get them from eth0 if the subnets are the same.

    repeat this (eth0:1) for each IP address.

    We have /etc/NetworkManger and inside this folder is folder VPN and folder dispatcher.d with no files in them.

    If you want assistance, please provide a full description of your setup (i.e distribution)

    Note, the correct path was /etc/network/interfaces

    Sorry.

    If you have /etc/NetworkManager, you're probably using RHEL/Fedora based distributions.

    In CentOS, it is something in the /etc/network/network-scripts.

    In the "/etc/sysconfig/network-scripts" directory

    Make a new file "ifcfg-eth0:0"

    add the following


    DEVICE=eth0:0

    BOOTPROTO=static

    ONBOOT=yes

    IPADDR="2nd IP address"

    GATEWAY="same GATEWAY IP as in file "ifcfg-eth0"

    NETMASK="same NETMASK as in file "ifcfg-eth0"



    Make a new file "ifcfg-eth0:1"

    add the following


    DEVICE=eth0:1

    BOOTPROTO=static

    ONBOOT=yes

    IPADDR="3rd IP address"

    GATEWAY="same GATEWAY IP as in file "ifcfg-eth0"

    NETMASK="same NETMASK as in file "ifcfg-eth0"





    Make a new file "ifcfg-eth0:2"

    add the following


    DEVICE=eth0:2

    BOOTPROTO=static

    ONBOOT=yes

    IPADDR="4th IP address"

    GATEWAY="same GATEWAY IP as in file "ifcfg-eth0"

    NETMASK="same NETMASK as in file "ifcfg-eth0"



    reboot server

    We where using CentOS 5 and had no network folder only NetworkManager. Ive reinstalled to Centos 6 and still no network folder only NetworkManger.

  • @Freelancenerds read @FrankZ post, it should be correct.

    Sorry I made my post just before you made yours. Ive found that path and will try.

    Good hunting. If you have any further questions just let us know :)

    Yes this worked. Thank you very much and also thanks to the other guys. ;)

    One more question.
    Would this also apply to IPV6?

  • FrankZFrankZ Veteran
    edited March 2014

    @Freelancenerds - All of your IPv6 addresses go in the "ifcfg-eth0" file and should look something like this...

    IPV6INIT=yes

    IPV6_AUTOCONF=no

    IPV6_DEFAULTGW="2604:bb60:badb:bb01:0000:0000:0000:0001"

    IPV6ADDR_SECONDARIES="2604:bb60:badb:bb01:dead:beef:0000:100a/64"

    multiple IPv6 addresses can go in the "IPV6ADDR_SECONDARIES=" with a space in between each address.

    OK, thanks again.
