What Is My DNS Server

DNS check that shows the resolver your connection really uses: operator, country, whether it is your ISP, a public resolver or a VPN, and whether lookups leak abroad.

What's My IP

What is my IP tool showing your public IP address, forwarded headers and connection details.

BDIX Speed Test

BDIX speed test measuring your download speed and latency to the origin: no app, runs in your browser.

BDIX IP Lookup

BDIX IP lookup that resolves any private IP (like 10.16.x.y) to its server, ISP and reachability.

BDIX Bandwidth Calculator

Bandwidth calculator to convert Mbps to MB/s and estimate download time for any file size.

BDIX Port Checker

Port checker that tests whether a BDIX server port (21, 80, 8080, 443) is open from our probe host.

Bangladesh USSD Codes

Bangladesh USSD codes to check balance, data and internet packs on Grameenphone, Robi, Banglalink and Teletalk.

Connection diagnostics (Internet Diagnostic, BDIX Speed Test, BDIX Tester, IPv6 Test, What's My IP, What Is My DNS Server) measure your local line, latency, and peering status. Network lookup and probe tools (BDIX IP Lookup, BDIX Port Checker) identify server hosts and verify open ports. Decision and calculation tools (ISP & Package Finder, BDIX Bandwidth Calculator) estimate download times and help match your household with top broadband plans. Reference guides (Router Login Finder, Bangladesh USSD Codes) provide default router logins and mobile operator USSD codes.

Every tool runs directly in your web browser without installing an app or signing up for an account, and results can be bookmarked or shared via direct URL.

FAQ (Frequently Asked Questions)

Are these internet tools free?

Yes. Every tool on this page is free and none of them needs an account or a signup.

Do I need to install an app to use these tools?

No. They all run in a normal web browser on desktop or mobile. The tests that run on your own connection (speed test, IPv6 test, BDIX tester) need JavaScript enabled, which is the browser default.

Do the tools work outside Bangladesh?

Most do. The bandwidth calculator, IP lookup and DNS tools work globally. The BDIX tools (speed test, IP lookup, port checker, BDIX tester) are about Bangladeshi ISP networks, so they are most useful on a BDIX-peered connection.

Which tool should I run first if my internet feels slow?

Run the Internet Diagnostic. It checks download speed, latency, DNS, IPv6 and BDIX peering in one pass, then tells you in plain English whether the problem sits in your local line or on the international route.

What is BDIX?

BDIX is the Bangladesh Internet Exchange, where Bangladeshi ISPs exchange traffic locally instead of routing it abroad. That is why the BDIX tools here measure local latency and private 10.x addresses rather than public internet hosts.
