Fix Recommendation

Configure the DNS server to separate internal and external roles to protect private address space.

Check Contents

Review the zone configuration with the DNS administrator and verify whether the zone has records on both the internal and external networks. If the zone is split, verify there is a separate external name server to handle the host records for external address space and an internal name server to handle the host records for internal address space.

If there are split zones and there are not internal and external roles to protect private address space, this is a finding.
