Windows 7 "warning: IPv6 protocol not available"

[Jefferson Carpenter]

Hello,

I'm trying to run an Unbound server on my PC for the purpose of 
accessing Namecoin's .bit domains.  Here's my full service.conf file:

# Unbound configuration file on windows.
# See example.conf for more settings and syntax
server:
     # verbosity level 0-4 of logging
     verbosity: 0

     # if you want to log to a file use
     #logfile: "C:\unbound.log"

     # on Windows, this setting makes reports go into the Application log
     # found in ControlPanels - System tasks - Logs
     #use-syslog: yes

     do-not-query-localhost: no
     domain-insecure: bit.
     interface: fe80::9181:5322:6eee:5dd8::
     access-control: fe80::9181:5322:6eee:5dd8::/80 allow
     interface: 192.168.1.100
     access-control: 192.168.1.0/8 allow
stub-zone:
     name: bit.
     stub-addr: 192.168.1.2 at 5300

Having added the IPv6 "interface" and "access-control" lines, I am now 
getting the error "[1511170420] unbound.exe[3504:0] warning: IPv6 
protocol not available".

I'm running on Windows 7.

Any help would be appreciated.
