split-dns

Split DNS is a configuration where internal and external DNS zones serve different records for the same domain, allowing internal users to resolve private IP addresses while external users see public addresses. On Windows Server, this is commonly implemented using separate DNS zones or conditional forwarders to ensure Active Directory and internal services remain accessible without exposing internal network details. The tagged content covers Windows Server DNS setup, including installation, configuration, security hardening, and troubleshooting, with split DNS as a key scenario for managing internal and external name resolution. Administrators use split DNS to improve security, reduce latency, and maintain seamless access to internal resources.
