[Unbound-users] How to config whitelist for EDNS client subnet in unbound

Thu Dec 18 08:21:36 CET 2014

Hi all,
I downloaded the code from and configured
unbound with "--enable-subnet".
Initial test shows that unbound indeed can process ECS queries but I cannot
figure out how to config a white list of servers that support ECS in the
config file.
I have gone through all the documentation and readmes but found nothing.
Can someone kindly show me how to do this?
Any help would be highly appreciated.
