What is Fake-IP

Fake-IP is a DNS resolution strategy used by proxy tools like Clash (Mihomo), Clash Verge, and similar transparent proxy software. Instead of performing a real DNS lookup when an application requests a domain, the proxy immediately returns a fabricated IP address from a reserved subnet (typically 198.18.0.0/16). The proxy maintains an internal mapping table between these fake IPs and the original domains, so when traffic is later routed to a fake IP, the proxy knows which domain the traffic was actually destined for.
