adig: Use a specific TCP port to connect to a DNS server.
$ adig -T ${port} ${example-com}
try on your machine
The command "adig -T ${port} ${example-com}" is used for performing a DNS lookup using the adig tool. Here is a breakdown of its parts:
- "adig": This is the name of the tool or command-line program that is being executed.
- "-T": This option specifies that TCP (Transmission Control Protocol) should be used for the DNS lookup. The "-T" flag is often used when a DNS query response is larger than the default UDP (User Datagram Protocol) packet size limit, which is 512 bytes.
- "${port}": This is a placeholder for the port number that should be used for the DNS query. Port numbers are used to identify specific services or processes running on a computer. You can replace "${port}" with the actual port number to be used in the command.
- "${example-com}": This is a placeholder for the domain name or hostname that you want to perform the DNS lookup on. You can replace "${example-com}" with the actual domain name or hostname that you want to query.
So, when you execute the command with the appropriate values for the port and domain name/hostname, it will initiate a TCP-based DNS lookup for the specified domain name or hostname using the specified port number.

never run a command you are not sure if it is safe.
