Network Diagnostic Tools
Analyze, diagnose, and troubleshoot your network. Perform a DNS lookup, run a Ping test, or check security with our Port scanner.
DNS Lookup
Query global DNS records (A, MX, CNAME, TXT) for any domain.
Ping Test
Check server reachability and response time from multiple locations.
Traceroute
Trace the path packets take across the internet to reach a host.
Port Scanner
Scan a server IP or domain for open ports (21, 22, 80, 443, etc.).
SSL Checker
Verify SSL/TLS certificate validity, issuer, and expiration date.
Speed Test
Measure your internet connection bandwidth, latency, and jitter.

Network Diagnostics FAQ
What is a Ping test?
A Ping test measures the time (latency) it takes for a data packet to travel from your device to a server and back. Lower latency means a faster connection.
How does Traceroute work?
Traceroute maps the journey of data packets across the internet, showing each 'hop' (router) between your computer and the destination server. It helps identify network congestion.
Why scan for open ports?
Scanning for open ports helps identify running services on a server and potential security vulnerabilities. Open ports can be entry points for attackers if not properly secured.
What does DNS Lookup do?
DNS Lookup retrieves record information (like A, MX, CNAME) from a domain's authoritative name server, helping verify that a domain is pointing to the correct IP address.
Is the SSL Checker reliable?
Yes, our SSL Checker fetches the live certificate chain from the server to verify its validity, issuer trustworthiness, and expiration date.
