🔍 What Is SubDNS-UI?

SubDNS-UI is a modern Subdomain + DNS Enumeration Tool built using Python and Streamlit — designed for reconnaissance, red teaming, bug bounty hunting, and ethical hacking.

The tool combines:

  • ✅ Subdomain brute-force detection
  • 🌐 DNS records enumeration (A, MX, TXT, etc.)
  • 📄 Markdown report generation
  • 🎨 Clean Streamlit-based UI
  • 💻 Instant on-screen results + download

✨ Key Features

  • 🛰️ Subdomain Enumeration using a wordlist
  • 🌐 DNS Records Resolver (A, AAAA, MX, TXT, SOA, CNAME)
  • 🧠 Multithreaded Scanning for speed
  • 📄 Auto-generated Markdown report
  • 🎨 Intuitive and lightweight Streamlit UI
  • ☁️ Download your results in one click

⚙️ What the Tool Does

🛰️ Subdomain Enumeration

  • Uses a custom wordlist (subdomains.txt)
  • Checks http:// and https:// availability
  • Uses multithreading for speed
  • Displays all live subdomains in the UI and report

🌐 DNS Record Extraction

  • Uses dnspython to query:
  • A
  • AAAA
  • MX
  • TXT
  • SOA
  • CNAME
  • Output shown in collapsible sections in the UI

📄 Markdown Report

  • All results (subs + DNS) are saved in a markdown file
  • Download directly from the browser via Streamlit

📂 Sample Wordlist (subdomains.txt)

www
mail
ftp
admin
dev
api
cdn
test
staging

You can easily replace or expand it with your custom wordlist.
