System prefers auto-generated IPv6 address over configured one
I have a number of systems with various flavors of Windows 7 installed - x64, x86, Home Premium, Ultimate, and so on. Some were factory installs, some were installed by me at various times.
Although I manually configured an IPv6 address on each system, they all exhibit the problem of using an automatically-generated IPv6 address instead of the one I have configured. This makes it difficult to connect to servers which use IP addresses for access control, as the automatically-generated addresses change on reboot.
Here's the output of ipconfig/all:
Note that the system lists 3 IPv6 addresses, one which I have hard-coded, an auto-generated one marked "preferred" and another auto-generated one which is not marked "preferred". When I try to access another IPv6 host on the same LAN, the connection comes from the 2430:1432:1:2:60ee:fe68:8697:cf8a address.Code:Windows IP Configuration Host Name . . . . . . . . . . . . : office Primary Dns Suffix . . . . . . . : Node Type . . . . . . . . . . . . : Hybrid IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No DNS Suffix Search List. . . . . . : tmk.com Ethernet adapter Bluetooth Network Connection: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Bluetooth Device (Personal Area Network) Physical Address. . . . . . . . . : 00-1B-DC-0F-6C-D0 DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Intel(R) 82567LM-3 Gigabit Network Connection Physical Address. . . . . . . . . : 00-22-19-1D-FE-43 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes IPv6 Address. . . . . . . . . . . : 2430:1432:1:2::51(Preferred) IPv6 Address. . . . . . . . . . . : 2430:1432:1:2:7cbd:6207:7849:c5ba(Preferred) Temporary IPv6 Address. . . . . . : 2430:1432:1:2:60ee:fe68:8697:cf8a(Preferred) Link-local IPv6 Address . . . . . : fe80::7cbd:6207:7849:c5ba%10(Preferred) IPv4 Address. . . . . . . . . . . : 10.4.35.51(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 2430:1432:1:2::1 fe80::219:e8ff:fee8:56ff%10 10.4.35.1 DNS Servers . . . . . . . . . . . : 10.4.35.61 10.4.40.135 NetBIOS over Tcpip. . . . . . . . : Enabled Tunnel adapter isatap.{F4779738-7244-4B7D-B0B4-62247E5B16CC}: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Microsoft ISATAP Adapter Physical Address. . . . . . . . . : 00-00-00-00-00-00-00-E0 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes Tunnel adapter Local Area Connection* 9: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Teredo Tunneling Pseudo-Interface Physical Address. . . . . . . . . : 00-00-00-00-00-00-00-E0 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes IPv6 Address. . . . . . . . . . . : 2001:0:4137:9e76:3cd1:d37:3372:dccc(Preferred) Link-local IPv6 Address . . . . . : fe80::3cd1:d37:3372:dccc%13(Preferred) Default Gateway . . . . . . . . . : NetBIOS over Tcpip. . . . . . . . : Disabled Tunnel adapter isatap.{069EB6C1-BDF6-402F-8F22-A2F780C0FC2B}: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Microsoft ISATAP Adapter #2 Physical Address. . . . . . . . . : 00-00-00-00-00-00-00-E0 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes
I've searched for a way to force Windows to use the IPv6 address I configured and I haven't found anything that worked.
