[Zope-Checkins] CVS: Zope/lib/python/ZServer - datatypes.py:1.4

[Fred L. Drake, Jr.]

Update of /cvs-repository/Zope/lib/python/ZServer
In directory cvs.zope.org:/tmp/cvs-serv26903

Modified Files:
	datatypes.py 
Log Message:
Medusa wants the IP number, not the actual hostname, so give it that
way.  We do more work up front, but this makes the pieces go together
more cleanly in the end since expectations aren't fudged.
