Features for Professionals #

• Live output streaming during tests
• One-click copy of command results
• Command history for quick repeat tests
• Summary cards with performance metrics (e.g., response time, packet loss)

Common Use Cases #

• Troubleshooting website connection problems
• Confirming a server is online
• Investigating slow page load times
• Verifying DNS configuration (A, CNAME, MX, etc.)
• Identifying routing or hop issues
• Testing general internet connectivity
• Checking WHOIS and domain registration details

Tips #

• Start with a simple connectivity test (ping)
• Use DNS checks if a domain resolves incorrectly
• Run traceroute to see where delays happen along the path
• Save time by re-running commands from your history

Related Tools #

• Ping: Measures response time and packet loss
• DNS Lookup (nslookup/dig): Checks DNS records and resolution
• Traceroute: Shows the path and hops to a target
• WHOIS: Displays domain owner and registration info

Troubleshooting #

• High ping times: Check local network, try another network, or run traceroute
• Packet loss: Verify your ISP or router, test at different times
• DNS errors: Confirm nameserver settings and record values
• Timeouts: Ensure the domain/server is online and reachable

Where to Find It? #
