 DNSMORPH is a domain name permutation engine, inspired by [dnstwist](https://github.com/elceef/dnstwist). It is written in [Go](https://golang.org/) making for a compact and **very** fast tool. It robustly handles any domain or subdomain supplied and provides a number of configuration options to tune permutation runs.
