A small utility for Linux-using web developers who can't be bothered to do flush dns on their router and everything or wait for DNS to propagate.
It makes it easy to add temporary DNS entries in /etc/hosts. You can use the CLI interactive menu to easily add and remove hostname mappings with hardcoded IPs.
The original file is backed up. This version only allows hardcoded IPs, since that's all I personally needed. Ideal when managing one main or migration process.
