Extract URLs / Emails / IPs

How the URL/Email/IP Extractor Works

What the Tool Does

The Extractor tool scans a block of text and pulls out all URLs, email addresses, and IP addresses it finds, presenting each category as a deduplicated, copyable list. This saves the manual effort of scanning logs, documents, or HTML source for specific patterns and is especially useful in security analysis, data cleaning, and content auditing workflows.

Common Developer Use Cases

Security analysts extract IPs and URLs from firewall logs, malware reports, and phishing emails to build IoC lists. Developers use it to pull all hyperlinks from a scraped web page, extract email addresses from a CSV export, or find all IP addresses mentioned in a configuration file. Content editors use it to audit external links in documentation before publication.

Data Formats, Types, or Variants

The tool uses regular expressions to match HTTP and HTTPS URLs (including those with query strings and fragments), RFC 5322-style email addresses (local-part@domain), IPv4 addresses in dotted-decimal notation, and IPv6 addresses in standard colon-hex notation. Defanged variants (e.g., hxxps:// or 192[.]168[.]1[.]1) may not be detected automatically — fang them first using the Defang/Fang tool.

Common Pitfalls and Edge Cases

Regex-based extraction can produce false positives (e.g., version numbers like 1.2.3.4 matched as IPs) and false negatives (unusual TLDs or internationalized domain names may be missed). Very long URLs with complex query strings may be truncated at word-boundary characters. Always review extracted results before using them in automated systems.

When to Use This Tool vs Code

Use this browser tool for quick ad-hoc extraction from pasted text. For bulk processing of files or streams, use dedicated libraries such as iocextract or urlextract (Python) or write a pipeline with grep and standard regex so extraction is reproducible and auditable.
