All you have to do is move the validation to a machine you
control to detect this garbage.
dnssec-enable yes;
dnssec-validation yes;
forward only;
forwarders { <Verizon's caching servers>; };
dnssec-lookaside . trust-anchor <dlv registry>;
All lookups which Verizon has interfered with from signed zones
will fail.
