We should try to ensure that IP number, DNS name and any alias will 
all work and be treated as a valid check.  not try to only directly 
match what is presented.  As we note Opensim uses numbers sometimes 
even where configurations give DNS names.

So one thing we ought to check is that the tests are not trying to 
limit the verification check to a DNS name where its given in some 
parts of Opensim versus an IP address where Opensim uses that in 
another context.  We note IP numbers for the machines we run our grid 
and sims on are often presented as IP numbers in the Opensim.log 
whereas we always use a DNS name such as virtual.aiai.ed.ac.uk in our 
config files throughout, including in region.ini files.  So Opensim 
is getting the underlying IP number and using it in some way even 
where the config gives a DNS name.

Of course the DNS name must be reverse lookupable from the number and 
vice versa, we understand that.  In fact we always use "service" 
aliases which are again reverse lookupable.  The underlying machine 
name has these are aliases.

See our example by using
      nslookup virtual.aiai.ed.ac.uk

Name:    killegray.aiai.ed.ac.uk
Address:  129.215.219.138
Aliases:  virtual.aiai.ed.ac.uk
