"IPv4 only intranet" meaning? RRS feed

  • Question

  • Hi,

    We always see "IPv4 only intranet" on NAT64/DNS64. I want to know exactly what it mean?

    If intranet network device does not support IPv6, but there are Windows 2008 server in intranet. Is it "IPv4 only"?

    And install Sharepoint and Dynamic CRM on Windows 2008, do Sharepoint 2010 and Dynamic CRM support IPv6?

  • It means that you are not using IPv6 on your internal network.

    If you were using IPv6 on your internal servers, you can connect via DirectAccess without using the NAT64 feature.

    It is possible to have a mix and match approach where some hosts are configured with both IPv4 and IPv6 addressing (often called dual stack). In this scenario, NAT64 is only used for hosts that are IPv4 only.

    SharePoint definitely supports IPv6 (IIS really) but I would be very surprised if Dynamics doesn't...

    Cheers

  • One way to determine if the CRM application supports IPv6 (assuming that it is installed on an IPv6 capable OS that has been assigned both IPv6 and IPv4 addresses) is to see if you can connect to it. If not, remove the IPv6 address and try again.

  • If you were using IPv6 on your internal servers, you can connect via DirectAccess without using the NAT64 feature.

    About this, My conclusions are:

    1. If internal server and app use IPv6 and internal network network device(switch, router..etc) does not support IPv6, the internal server will use ISATAP and DA client can connect without using NAT64.
    2. If internal server and app use IPv6 and internal network device support/enable IPv6, DA client can direct connect by IPv6 without using NAT64.

    Am I correct?

  • That is correct.

    NAT64 is used only when the internal server OS itself doesn't support IPv6 or when ISATAP is disabled

  • Hi Jason Jones,

    I would like to know about the solutions for IPv6 with Dynamics CRM.

    SharePoint definitely supports IPv6 (IIS really) but I would be very surprised if Dynamics doesn't...

    What does this mean? That you want to confirm IPv6 complient with CRM.

    I already know about Microsoft Dynamics CRM 4.0 does not support IPv6. But i really would like to know how about CRM2011 Online?

     

    Thanks in advance.

    Regards,

  • Yeah, I assumed CRM 4.0 would be IPv6 compatible; guess I was wrong :(

    Not sure about CRM2011...but, one would hope so :)

    Cheers
