## What it is
A community-maintained reference list of services vulnerable to subdomain takeover via dangling DNS records, with guidance on how to claim affected (sub)domains. It serves as a knowledge base for security researchers and bug bounty hunters rather than a runnable tool.

## Use cases
- check if a service is vulnerable to subdomain takeover
- find how to claim a dangling CNAME record
- research subdomain takeover techniques for bug bounties
- verify whether a DNS record points to a claimable service
- learn about subdomain takeover vulnerabilities

## When to choose
- you need an up-to-date reference of takeover-vulnerable services
- you are doing bug bounty recon and want to assess dangling DNS records
- you want guidance on safely demonstrating a takeover

## When to avoid
- you need an automated subdomain takeover scanner
- you want a tool rather than a curated list
- you need guaranteed accuracy for every entry

## Facets
- artifact type: dataset
- maturity: active
- function: security, vulnerability-scanning, documentation
- domain: security, penetration-testing, developer-tools
- platform: cross-platform
- tags: subdomain-takeover, bug-bounty, dns, infosec, reference-list
