⚙️ BGP Autonomous System (ASN) Routing, CGNAT & Geolocation Diagnostics
Every packet crossing the internet carries a source IPv4 (32-bit) or IPv6 (128-bit) header routed via Border Gateway Protocol (BGP) across Autonomous Systems (ASNs). Inspecting your public IP reveals how external servers, firewalls, and content delivery networks classify your connection.
DH Tools queries real-time RIR (RIPE, ARIN, APNIC) allocation metadata to display your public IP, ASN organization, country/city coordinates, and timezone—helping you verify VPN tunnels, diagnose CGNAT port-forwarding blocks, and whitelist remote IPs.
📊 Technical Specifications & Architecture
| Protocols | IPv4 (32-Bit) & IPv6 (128-Bit Hex) |
|---|---|
| Metadata | ISP Name, BGP ASN, Country, City, Timezone |
| Map Engine | Interactive Coordinate Pinpointing |
| Use Case | VPN Audit, Firewall Whitelisting & CGNAT Check |
🎯 Real-World Industry Use Cases
✓ VPN & Proxy Leak Verification
Confirm your residential ISP and city are masked before browsing on public Wi-Fi.
✓ Server & Firewall Whitelisting
Copy your current public IPv4 address to authorize SSH, RDP, or AWS security group access.
✓ CGNAT Port Forwarding Diagnosis
Compare your router's WAN IP against your Public IP to detect Carrier-Grade NAT.
✓ Suspicious Log Investigation
Look up unknown IP addresses from server access logs to identify datacenter bots or regions.
