+- Gateway: Next hop IP address (or "-" if direct)
+- Interface: Network interface name

+- Protocol: Routing protocol (kernel, static, dhcp, etc.)
+- Scope: Route scope (global, link, host, etc.)
+- Type: Route type (unicast, local, broadcast, etc.)
+- Table: Routing table name (main, local, netbird, etc.)

+- Resolved domain names that matched those patterns
+- IP address prefixes that were resolved for each domain
+- Parent domain associations showing which original pattern each resolved domain belongs to
