The following name servers were found as part of EDNS compliance
checking <https://ednscomp.isc.org/compliance/tld-report.html#e1>.
They ignore the EDNS version field in the request and return a SOA
as if the version field was set to zero rather than 1. Correctly
functioning name servers will return BADVERS to EDNS version 1
requests with the version field set to the highest version that
they support. Can you please fix these server. You name server
vendor most probably has a fixed version of the name server code
that you can install.
