This is how I implement "local" dns.  Have a local dns server for local 
resolution.  No dependency on a name server that might need to be broought 
down for maintenance or is having network connectivity issues.  You can 
use split views on one dns server to accomplish this, but given the low 
cost of moderately performing hardware an internal dns server is 
reasonable.

the only domainless way I'm aware of is thru host files and keeping them 
up to date is problematic.
