-// How it works:
-// 1. When a DNS query arrives, the proxy first checks its local record store
-// 2. If a matching A or AAAA record exists locally, it returns that immediately
-// 3. If no local record exists, it forwards the query to upstream DNS (8.8.8.8 or 8.8.4.4)
-// 4. All other DNS record types (MX, CNAME, TXT, etc.) are always forwarded upstream
