Ubuntu Desktop dns binding help

[Joseph Sinclair]

I would assume that he's talking about broad testing within a local network, rather than testing against localhost directly.
I often do this because I can insert firewalls, routers, etc... as/where desired to emulate probable scenarios.  It's particularly helpful to emulate 4in6 or 6in4 connections when using external providers that do not provide sufficient IPv6 support.

It's just easier to create a hostfile entry on the test client(s) than to create or modify public DNS (sometimes that's not even possible).  This is particularly true when the service you're testing is already live and you need to black-box test a component of an interconnected SOA system.
