Troubleshooting network connectivity and configuring interfaces in 🪟 Windows 11 is handled by a set of command-line tools:

Displays active network adapter IP details.

ipconfig /all: Lists full configuration info including DHCP leases, DNS servers, and MAC address.
ipconfig /flushdns: Purges the local DNS resolver cache (crucial when a website changes IPs and you are stuck seeing the old cached site!).
ipconfig /release & ipconfig /renew: Releases and requests a new IP address from the DHCP server.

Sends ICMP Echo Requests to verify a remote server's availability and latency:

ping -t [address]: Pings the target host continuously (press Ctrl + C to stop and view statistics).
ping -n 10 [address]: Pings the address exactly 10 times.
ping -a [IP]: Attempts to resolve the IP address to a computer hostname.
