Working with SubFinder

Here we will find out subdomains of the domain geeksforgeeks.org and setting a concurrency of 50. I got around 73 subdomains for geeksforgeeks.org in 4 seconds 71 milliseconds.

subfinder -d geeksforgeeks.org -silent -t 50

Example usage of subfinder

Pros of subfinder over sublist3r: As subfinder is a Go Tool and sublist3r is a python tool and Go Language is faster than python and also Go language’s approach to concurrency is very easy to work with. Also, subfinder also provides various options that sublist3r doesn’t.
