# Online DNS & Subdomain Recon Tools
Collection of **web-based / online** DNS tools useful during the reconnaissance phase of penetration testing and security assessments.
These tools focus on:
- DNS record lookups and analysis
- Subdomain enumeration
- DNS propagation checking
- Delegation and DNSSEC validation
- Historical reverse DNS records
- Wildcard / testing DNS services
They complement CLI-based recon tools (see [pentest-arsenal.md](./pentest-arsenal.md)) and are ideal for quick, passive OSINT without local installation.
