Welcome to Zone2Host
Isn't that going backwards?
There are times when a hosts file is more appropritate than relying on DNS. Some networks are closed and don't have access to the DNS servers. Some machines are critical to an organization and need to continue to work on host names, even if there is a DNS outage.
I was looking for a good way to manage IP addressing and computer names on a network that couldn't rely on DNS. The problem was, the best management tools were designed for administering a zone. So rather than roll my own management tools, I cooked up Zone2Host to convert the zone files into the hosts files I needed.
