# Fastsub
A custom built DNS bruteforcer with multi-threading, and handling of bad resolvers.
Authored by Michael Skelton (@codingo_), Luke Stephens (@hakluke), and Sajeeb Lohani (@sml555_)
# Usage
## Threads
Always insure that the number of threads being used isn't more than 2x the number of cores in the destination machine, if so the application will still work but will have a performance hit, rather than benefit. You can check the number of cores with `nproc`.
```
