DNS

NO_CLIENT_SITE entries in Netlogon logs are useful evidence that client networks are not mapped cleanly to Active Directory sites. PowerShell can turn the logs into a subnet-hygiene report.

When private sites and DNS exceptions multiply, WARP device-profile configuration becomes data. Source control can become the input and PowerShell the generator.

Static IP and subnet rules become fragile when SaaS platforms and CDNs move underneath you. Domain-aware egress policy aligns network controls with application intent.

The simple 301 redirect pattern I use to keep one canonical hostname for a site.

Cloud and SaaS services move between addresses. Policy often expresses intent more accurately when it follows the application hostname.

DNS resolution and packet routing are related, but a WARP configuration often needs you to reason about them separately.
