What Is IP Address Extractor?

The IP Address Extractor scans text and finds both IPv4 and IPv6 addresses. IPv4 addresses are validated to ensure each octet is in the 0-255 range. IPv6 addresses in full notation are detected. Results are categorized by IP version and deduplicated. This tool is useful for network analysis, log parsing, security audits, and extracting server addresses from documentation.

Why Use Our IP Address Extractor?

  • Extract both IPv4 and IPv6 addresses from text
  • IPv4 octet validation (0-255 range)
  • Results categorized by IP version
  • Deduplication of found addresses

Common Use Cases

Log Analysis

Extract IP addresses from server logs for analysis.

Network Audit

Find all IP addresses mentioned in network documentation.

Security

Identify IP addresses in security reports or incident logs.

Configuration

Extract IP addresses from configuration files.

Technical Guide

The extractor uses separate patterns for IPv4 and IPv6. The IPv4 pattern uses word boundaries and validates each octet: /\b(?:(?:25[0-5]|2[0-4]\d|[01]?\d\d?)\.){3}(?:25[0-5]|2[0-4]\d|[01]?\d\d?)\b/g. This ensures octets do not exceed 255. The IPv6 pattern matches full notation: /(?:[0-9a-fA-F]{1,4}:){7}[0-9a-fA-F]{1,4}/g. A shortened IPv6 pattern also matches addresses with trailing colons indicating compressed format. Results are categorized as IPv4 or IPv6 and deduplicated using Set.

Tips & Best Practices

  • 1
    IPv4 addresses are validated for correct octet ranges (0-255)
  • 2
    Full and abbreviated IPv6 formats are detected
  • 3
    Results are grouped by IP version
  • 4
    Word boundaries prevent partial matches in longer numbers
