We’ll demonstrate IPCONFIG, NSLOOKUP, PING, TRACERT, PATHPING, NBTSTAT, and NETSTAT. We’ll also give you some best practices for troubleshooting network interfaces, protocols, and firewalls.

      Jonathan – If an IP address is an internally assigned address from a DHCP server, you can check the DHCP server logs to determine who received the address. If the address is public, you can query the ARIN database to determine who owns the IP address.
