Does this skill support local network inspection?

Yes, it includes tools to list local network interfaces, view routing tables, check ARP caches, and identify your public IP address.

How does it help with API development?

It allows you to test endpoints using the HTTP request tool, verify SSL certificates are valid, and ensure the target ports are open and reachable.

Can it identify where network lag is occurring?

Yes, by using the traceroute and latency tools, you can pinpoint specific hops or network segments causing delays or packet loss.

What network tests can I perform with this skill?

You can perform ICMP pings, DNS lookups, port scans, traceroutes, WHOIS lookups, SSL certificate checks, and HTTP/WebSocket connectivity tests.
