Performs a forward lookup and displays the IP address of the domain www.c3scripts.com. Currently, the IP address of this domain is [18.104.22.168].
Performs a reverse lookup of the IP address [22.214.171.124] and displays its domain name. Currently, a reverse lookup of this IP returns server.c3server.com.
