  • 1.  Prefer ipv4 over ipv6 on a dual-stack ESXi host?

    Posted Jul 07, 2017 01:37 PM

    I can't believe I am the first one to ask this question, but search here and on the Internet in general did not produce any hits.

    OMB mandated Fed Gov to enable dual stack which we complied with in my environment to include esxi 5.5 hosts

    We still want to prefer ipv4 for everything, since we are not ready to go ipv6 only, and we want to avoid having some services using one stack and other services using the other. This creates extra overhead, complexity, troubleshooting issues, etc.

    Right now we are dealing with the fact that a dual-stack esxi host uses ipv6 for syslog. While there are tons of info on how to prefer ipv4 on dual-stack Linux servers, there is nothing for ESXi.

    Any help would be appreciated.

    According to KB Deploying vCenter High Availability with network addresses in separate subnets (2148442) - In vCenter Server 6.5, using dual IP stacks (IPv4 and IPv6) is not supported.

    Well, that KB is only for a vCenter HA deployment. Other deployements of vCenter support dual stack.
