try on your machine

The command dig -x ${8-8-8-8} is using the dig command-line tool to perform a reverse DNS lookup for the IP address represented by 8.8.8.8, which is a commonly used Google Public DNS server.

Let's break down the command:

dig is a command-line tool used for DNS (Domain Name System) lookup operations.
-x is an option for the dig command that specifies a reverse DNS lookup, which means it will give you the domain name associated with the given IP address.
${8-8-8-8} is a parameter expansion that substitutes the IP address 8.8.8.8 in place of ${8-8-8-8}.

In summary, the command is asking the DNS system to provide the domain name associated with the IP address 8.8.8.8 using the dig tool.
