SRG-APP-000251-DNS-000037
Group -
The Windows 2012 DNS Server must be configured to only allow zone information that reflects the environment for which it is authoritative, to include IP ranges and IP versions.
DNS zone data for which a Windows 2012 DNS server is authoritative should represent the network for which it is responsible. If a Windows 2012 DNS server hosts zone records for other networks or en...Rule Medium Severity -
