The command "ahost" is used to perform DNS (Domain Name System) lookups. It is commonly used to resolve domain names to IP addresses, and vice versa.
In the provided command, "ahost -d ${example-com}", the "-d" option is used to specify a reverse lookup. Reverse lookup involves retrieving the domain name associated with an IP address, rather than the usual mapping of domain name to IP address.
"${example-com}" is simply a placeholder indicating that you should replace it with an actual IP address in the command. For example, if you want to perform a reverse lookup for the IP address 192.168.1.1, you would modify the command as follows: "ahost -d 192.168.1.1".
By executing this command, the system will perform a reverse DNS lookup to determine the domain name associated with the provided IP address.
