IPv6 DHCP, no scope, yet giving out addresses RRS feed

  • Question

  • Hi,

    I've got an issue with a Server 2008 machine which is giving out IPv6 addressess. I know lots of people on the forum would love to have this, but I haven't configured a scope for IPv6. I do have a scope for IP4 which is working like a charm.

    How can I stop the IPv6 DHCP-server from giving out ip-addresses?

    Regards,
    Thijs

    Windows Server® 2008 supports stateless and stateful DHCPv6 server functionality. DHCPv6 stateless mode clients use DHCPv6 to obtain network configuration parameters other than the IPv6 address, such as DNS server addresses. Clients configure an IPv6 address through a non-DHCPv6 based mechanism such as IPv6 address auto-configuration (based on the IPv6 prefixes included in router advertisements), or static IP address configuration. In DHCPv6 stateful mode, clients acquire both the IPv6 address as well as other network configuration parameters through DHCPv6.

  • This link below is a blog on DHCPv6, this may prove useful when you need to add/ remove DHCP options from the server.

  • Thank you seansobey for your answer. The links weren't of any use, but informal. So it seems the 2008 Server and (in my case) Windows 7 use their own ip6-addresses and obtain the ip6-DNSserver in a different way.

    Something I'll have to study a bit more.

  • What you can do is on the NIC properties unslect the radio box for IPv6... This will stop the IPv6 requests
