[cs615asa] Question about HW2

Oops, sorry. Here it is:
-----
Quick question about semantics..

What counts for a hostname being resolved? Must it have an IP address, 
or just as long as something is returned from DNS?

example:

*stevens.edu:*
stevens.edu has address 155.246.21.38
stevens.edu mail is handled by 0 po.stevens.edu.
stevens.edu mail is handled by 0 box.stevens.edu.

*cs.stevens.edu:*
cs.stevens.edu mail is handled by 0 guinness.cs.stevens-tech.edu.

*asdf:*
Host asdf not found: 3(NXDOMAIN)


Would we say just the first one resolved, since it has an IP? Or the 
first 2 resolved, since DNS found something?

Thanks
-Sean
