router shows IP6 addrs for two clients; should not

Whats the point you're trying to make? Try not to speak in shorthand, helpers in here are from around the globe and won't understand less than plain english.

windows 7 - Getting an IPv6 repsonse when IPv6 interface is disabled. Why? - Super User



""It's normal for a resolver to report IPv6 addresses regardless of whether IPv6 is actually enabled on any interfaces. The resolver operates at the TCP and UDP layer, and isn't programmed to check whether or not addresses of a particular protocol family would ultimately be usable if they were returned. That would complicate the resolver a lot (consider cases where IPv6 may be available through one interface but not through another, and which interface gets uses for the traffic depends on routing), not to mention being a blatant layering violation.

When the resolver returns IPv6 addresses and they are not usable due to no interfaces having IPv6 connectivity, they will very quickly be rejected by the application's socket connection logic, so it costs almost nothing to return them and try them anyway.""

Thankyou, 3nd.

In my case, ip6 addrs are not reported "regardless of ...."
Reported for some interfaces, not for others.
At least we know that it is normal for the ones that I described. (if we were to accept the superuser.com comment)

To disable IPv6

Code:

netsh int ipv6 isatap set state disabled
netsh int teredo set state disabled
netsh interface ipv6 6to4 set state state=disabled undoonstop=disabled
reg add "HKLM\Software\Policies\Microsoft\Windows\TCPIP\v6Transition" /v "6to4_State" /t REG_SZ /d "Disabled" /f
reg add "HKLM\Software\Policies\Microsoft\Windows\TCPIP\v6Transition" /v "ISATAP_State" /t REG_SZ /d "Disabled" /f
reg add "HKLM\Software\Policies\Microsoft\Windows\TCPIP\v6Transition" /v "Teredo_State" /t REG_SZ /d "Disabled" /f
reg add "HKLM\System\CurrentControlSet\Services\Tcpip6\Parameters" /v "DisabledComponents" /t REG_DWORD /d "255" /f
reg add "HKLM\System\CurrentControlSet\Services\Tcpip6\Parameters" /v "EnableICSIPv6" /t REG_DWORD /d "255" /f
