All Domains with HTTP Response

All Active Domains Database — 170 Million+ HTTP Responding Websites

The All Active Domains (HTTP Responding) dataset from WebTrackly is one of the most comprehensive collections of verified, live websites available on the market. Containing over 170 million domains that actively respond to HTTP requests, this dataset goes far beyond a simple list of registered domain names. Every entry has been confirmed to host a functioning web server, meaning you are working exclusively with real, operational websites.

What Makes This Dataset Different from Zone Files?

Many data providers sell zone file extracts — raw lists of domains registered across various TLDs. While zone files are useful for understanding the domain registration landscape, they include millions of domains that are parked, expired, under construction, or simply not resolving to any live content. The gap between "registered" and "actually running a website" is enormous.

This dataset solves that problem. WebTrackly performs large-scale HTTP probing across the entire domain namespace, filtering out every domain that does not return a valid HTTP response. The result is a curated list of 170,835,843 domains that are genuinely active on the internet — sites with web servers, content, and real traffic potential. If a domain is in this list, it has a live website behind it.

Who Buys This Data?

This dataset serves a wide range of professional use cases:

• Lead generation companies rely on active domain lists to identify real businesses operating online. Instead of wasting time filtering out parked pages and placeholder sites, they start with a verified pool of live websites and enrich from there.
• Web scraping teams use this dataset as a target list for large-scale data collection. Knowing in advance that every domain responds to HTTP requests eliminates failed connections and dramatically improves crawl efficiency.
• Market researchers and analysts use the data to measure the size of the active internet, track the growth of web presence across industries and regions, and benchmark online adoption rates.
• Cybersecurity professionals leverage the dataset for reconnaissance, vulnerability scanning, and attack surface mapping across the live web.
• Domain investors and brokers analyze active domain patterns to spot trends, evaluate aftermarket potential, and identify niche markets with high website density.

Common Use Cases

The practical applications of a verified active domains database are extensive:

• Finding real businesses vs. parked domains: Sales and marketing teams waste significant resources contacting domain owners who have no active business. This dataset eliminates that noise entirely, providing only domains with live HTTP responses.
• Building web scraping target lists: Large-scale scraping operations need reliable seed lists. Starting with HTTP-verified domains means fewer timeouts, fewer errors, and higher data yield per crawl cycle.
• Market sizing of the active internet: Researchers studying internet growth, regional web adoption, or TLD popularity need accurate counts of live websites — not just registered names. This dataset provides ground-truth measurements.
• Competitive intelligence: Companies can analyze which domains are active in their vertical, discover new market entrants, and track the online footprint of competitors.

Data Fields Included

Each record in the dataset contains the domain name along with its HTTP response status, confirming that the domain is actively serving content. The dataset is delivered in convenient flat-file formats suitable for direct import into databases, analytics platforms, or custom pipelines. Records are structured for easy parsing and integration with existing workflows.
