Setting Multiple Shell Variables from One Run of awk

Right now, I have a shell script that does the following:

hostname=`echo $NEWDEV |awk 'BEGIN{FS="."}{print $1}'`
domain=`echo $NEWDEV |awk 'BEGIN{FS="."}{print $2}'`
top0=`echo $NEWDEV |awk 'BEGIN{FS="."}{print $3}'`
top1=`echo $NEWDEV |awk 'BEGIN{FS="."}{print $4}'`

That looks inefficient (dumb) so I ask, is there a way
to assign the fields in an awk expression to shell variables as
one runs awk once?

Being able to do that would mean one run of awk instead
of the 4 shown here and, if file accesses are involved, there is
only one of those.

Thanks.
