  • 1.  IP Address (Conflict) .. Due Diligence reqd

    Posted Feb 25, 2013 04:20 AM

    If a system engineer given a duplicate ip for the newly created virtual machine (given the gateway IP as VM's IP), obviously outage will happen.

    Is there a way to prevent the IP address conflict issue proactively?

    what are your thoughts on this?

    When in doubt, I try to ping the IP from any machine in the same network. Also, some OSs, such as Windows or Linux does report if you have a conflict.

    The only proactive way to prevent that, as far as I know, would be to use some IP Tracking tool. It is basically a spreadsheet which has all IP used. Either that or use DHCP :smileyhappy:

    Managing spreadsheet is a manual process. DHCP is a solution for Virtual Machines if they are client OS, but not for servers.

    look at : http://www.solarwinds.com/ip-address-manager.aspx

    There are dozen of tools similar to this one.

    You could also use DHCP in static mode with servers.

    Thanks for your input, but pinging the IP address is still a manual process
