Because that duplicates the data, which you then need to keep
synchronized. Yuck.
It looks like you might be able to get some use out of Ruby's "Resolv"
class, but that's a bit of a hack because it does not use the system's
native resolver library (hence it might provide different answers in some
cases).
I think a more reliable approach would be via Socket.getaddrinfo() or
Socket.gethostbyname(). As far as I can tell, those are direct interfaces
to appropriate system libraries, but they are probably somewhat trickier to
use.
