there are ways around thiswhen somebody sends an http inquire to macdonald.com
they then receive
restraunt.macdonald.com
store.macdonald.com
some domain
name software alreadys works this way ( nslookup )
also to know the difference
between the business macdonald and the person... a case sensitive search could be
done
MacDonald.com
again... domain name software does exist to do such also.
yet have not heard of a standard default
MacDonald.biz with case sensitive could
refer to the local family business of MacDonald or the non local business if
the local family does not exist or has yet to do the registry
