Q&A related to ping, traceroute, port scanner, whois and DNS query
- What does 'failed to resolve IP address' mean?
- Ping and traceroute don't work, what's wrong?
- Does the port scanner scan UDP ports?
- Why doesn't the ANY DNS query show all the records?
- What is the precision of traceroute and ping location reports?
- The port scanner shows some open ports even though I'm sure they are closed
