3️⃣ Why DNS Filtering?
When you type a website like `www.google.com`, your device actually contacts a DNS server
to find its **IP address** (like 142.250.64.78). NxFilter intercepts this request.
If the request is allowed → it sends the correct IP
If the site is blocked → it returns a “blocked” message or login screen
This allows NxFilter to act **before the browser even connects to the website**.
4️⃣ Use Cases
– In the office** – Block social media and distractions during work hours
– In schools** – Block adult sites, gaming, and YouTube
– By IT admins** – Track web activity and apply rules per user or group
– For security** – Prevent malware, phishing, or dangerous websites

Whether you’re blocking distractions, protecting kids, or increasing cybersecurity,
NxFilter is one of the easiest tools to deploy and manage.
