Bing-ip2hosts is a Bing.com web scraper that discovers hostnames by IP address. Bing is the flagship Microsoft search engine formerly known as MSN Search and Live Search.
This search engine provides a feature unique to search engines - it allows searching by IP address. To try this, go to Bing.com and search for IP:your-ip-here. It should show you results from microsoft.com. If it shows empty results, then add a single dot.
Unlike other Bing web scrapers that stop after scraping 10 result pages, bing-ip2hosts can scrape thousands of results. It continues scraping search result pages until it no longer finds new results. It can be used to discover subdomains and other related domains.
If you want to find websites being hosted on a single ip address. For example many websites run behind cloudflare but using a single ipaddress, this tool enumerates hostnames from bing for an IP address, this happens to be a feature unique with being alone.
Many websites are hosted into a single server with one ip, this could be Subdomains. Other services like cloudflare use a single ip to host many websites using it.
