c1350cf5bc50458ba79cc93ff9e0e5fe3f1aeeb0jeff.schenk With the release of BIND 9.11.0, ISC changed to the open

c1350cf5bc50458ba79cc93ff9e0e5fe3f1aeeb0jeff.schenk The MPL-2.0 license requires that if you make changes to

c1350cf5bc50458ba79cc93ff9e0e5fe3f1aeeb0jeff.schenk changes, therefore this change will be without consequence

Authoritative server support for the EDNS Client Subnet option
(ECS), introduced in BIND 9.11.0, was based on an early version
of the specification, and is now known to have incompatibilities
with other ECS implementations. It is also inefficient, requiring
a separate view for each answer, and is unable to correct for
overlapping subnets in the configuration. It is intended for
testing purposes but is not recommended for for production use.
This was not made sufficiently clear in the documentation at
the time of release.
