Digglet searches and lists subdomains from a target(s).
As it finds subdomains it indicates if they are obsolete or still in use.
At the end of the execution you will find a folder with the results obtained: file with all the subdomains, file with the active subdomains and another file with the obsolete subdomains of the target(s).
