What it shows

  • Serves distinct DNS records based on requester source IP address.
  • Internal staff resolve private RFC 1918 addresses without internet egress.
  • External clients receive public VIPs, hiding internal network topologies.

The takeaway

One domain name, two views: route internal users locally and external traffic publicly.
