ipmap

An open-source, cross-platform powerful network analysis tool for discovering websites hosted on specific IP addresses and ASN ranges.

Features

• ASN scanning (Autonomous System Number) with IPv4/IPv6 support
• IP block scanning (CIDR format)
• HTTPS/HTTP automatic fallback
• Chrome 131 TLS Fingerprint (JA3/JA4 spoofing via uTLS)
• Real Chrome Header Order (WAF bypass optimized)
• Referer Header Rotation (Google, Bing, DuckDuckGo)
• Firewall bypass techniques (IP shuffling, header randomization, smart jitter)
• Proxy support (HTTP/HTTPS/SOCKS5)
• Custom DNS servers
• Rate limiting (token bucket algorithm)
• Dynamic timeout calculation
• Text and JSON output formats
• Configurable concurrent workers (1-1000)
• Real-time progress bar
• Graceful Ctrl+C handling with result export
• Input validation (ASN, IP/CIDR format checking)
• Large CIDR block protection (max 1M IPs)

Usage

Parameters

-asn AS13335                         # Scan all IP blocks in the ASN
-ip 103.21.244.0/22                  # Scan specified IP blocks
-d example.com                       # Search for specific domain
-t 2000                              # Request timeout in ms (auto if not set)
--export                             # Auto-export results
-format json                         # Output format (text or json)
-workers 100                         # Concurrent workers (default: 100)
-v                                   # Verbose mode
-c                                   # Continue until completion
-proxy http://127.0.0.1:8080         # Proxy URL (HTTP/HTTPS/SOCKS5)
-rate 50                             # Rate limit (requests/sec, 0 = unlimited)
-dns 8.8.8.8,1.1.1.1                 # Custom DNS servers

Examples

# Basic ASN scan
ipmap -asn AS13335

# Find domain in ASN
ipmap -asn AS13335 -d example.com

# Scan IP blocks
ipmap -ip 103.21.244.0/22,103.22.200.0/22

# High-performance scan
ipmap -asn AS13335 -workers 200 -v

# With proxy and rate limiting
ipmap -asn AS13335 -proxy socks5://127.0.0.1:9050 -rate 50

# Full configuration
ipmap -asn AS13335 -d example.com -proxy http://127.0.0.1:8080 -rate 100 -workers 50 -dns 8.8.8.8 -v --export
