🤖 Overview

The IP Web Crawler is a legitimate web crawler operated by IP Web Crawler LLC, a company specializing in IP intelligence and threat detection services based in the United States. Its primary purpose is to collect publicly available web content to build and maintain an extensive database of IP geolocation, domain ownership, and web server metadata. This data feeds into their commercial products such as IP lookup APIs, threat intelligence feeds, and network mapping tools used by cybersecurity professionals and enterprise clients.

🌐 Technical Behavior

The crawler performs HTTP and HTTPS requests with a consistent crawl rate of approximately 10 requests per second per source IP, adhering to standard web crawling etiquette as documented on their official website ip-web-crawler.com. It uses a rotating set of IP addresses from multiple autonomous systems, including those registered to IP Web Crawler LLC and cloud providers like AWS and Google Cloud, to distribute load and avoid overwhelming single origins. The crawler always fetches robots.txt before initiating a crawl on a new domain and respects crawl-delay directives if present. It primarily targets pages containing IP addresses, domain names, or server headers, employing a depth-first crawl algorithm and limiting concurrent connections to two per domain.

📋 robots.txt Compliance

According to the official documentation published at ip-web-crawler.com/robots, the bot fully honors all Disallow directives specified in robots.txt files. It also respects meta robots tags (noindex, nofollow) and exits immediately upon encountering a disallowed path. No known reports or CVEs exist of the bot ignoring these standards.

🔍 Detection Indicators

The primary User-Agent string is "IP Web Crawler" or "ip-web-crawler.com", and a corresponding contact email is included in the User‑Agent field or via an HTTP From header: [email protected]. The bot also sets a custom HTTP header X-Crawler-Name: ip-web-crawler. Behavioral fingerprints include sequential crawling of page URLs with low variance in request timing and consistent Accept headers.

📊 Data Usage

Collected data is used to enrich IP intelligence databases that provide accurate geolocation coordinates, ISP ownership, and threat scores. The company’s threat intelligence feeds, updated daily, incorporate this crawl data to flag malicious IPs and support network security tools used by enterprises and government agencies.

⚙️ Rate Limiting Policy

Although the bot is legitimate and well‑behaved, its distributed crawling can generate a high volume of requests on popular sites, warranting threshold‑based rate limiting. Webmasters are advised to set a limit of 20 requests per minute per source IP to prevent resource exhaustion while still allowing the bot’s essential data collection.
