Network Checker

📡 Network Checker — Network Diagnostics & Connectivity Toolkit

Network Checker is a collection of networking tools designed around challenging internet connectivity conditions, particularly those involving DPI restrictions. It helps users investigate website accessibility, compare DNS performance, examine CDN connectivity, and prepare or modify supported proxy configurations.

🌍 Internet Diagnostics

Run a collection of network tests to investigate connectivity problems.

• Test supported network protocols and DNS providers • Check the accessibility of popular websites • Add custom domains for individual checks • Collect results for further analysis with your preferred AI assistant

🔎 Domain Checker & DNS Tools

Network Checker includes several tools for examining domain resolution and network response times.

• Domain Checker: Check whether selected domains are reachable from your current network. • DNS Latency Test: Compare response times from supported DNS providers. • DNS Hunter: Investigate how selected Iranian data centers resolve DNS requests for specific domains.

☁️ CDN & IP Scanning

Explore supported CDN address ranges and test connectivity to selected endpoints.

• Cloudflare Edge IP Checker: Scan for accessible Cloudflare edge IP addresses. • CDN Xray Scanner: Test CDN IP ranges using Xray-core and your own compatible JSON configuration. • Akamai Scanner: Scan supported Akamai IP ranges. • SNI Spoof Check: Test whether SNI spoofing appears usable on the current network.

Scanning results depend on the selected targets, network conditions, and configuration. A successful test does not guarantee that an address will work reliably for every service.

🔗 VLESS Configuration Modifier

Replace the IP address in a compatible VLESS configuration with addresses from a supplied list or IP range. The tool can generate multiple configurations for further testing.

🏗️ Netlify Configuration Generator

Generate multiple configurations from combinations of supplied SNI values and IP addresses, providing a convenient way to prepare variations for network testing.

📩 Android SMS Configuration Encoder

The Android version includes a configuration encoder that converts English text into a representation using Persian characters and can decode it on the receiving device. This can help transfer configuration text in environments where ordinary SMS content is restricted.

💻 Platform & Compatibility

Network Checker is available for Android, Windows, and Linux. Some tools require custom IP ranges, domain lists, or an Xray JSON configuration. Large scans may require additional system resources or platform-specific adjustments.

📜 License

Network Checker is released under the GNU General Public License v3.0 (GPL-3.0).

⚠️ Important

Network Checker is a diagnostic toolkit, not a VPN provider. It does not supply guaranteed working servers or subscriptions. Use trusted configurations and scan only systems and address ranges you are authorized to test.

✨ Investigate connectivity, compare network results, and make better-informed configuration choices.
