% Our domain name is
% We want to create a subdomain called
% Our subdomain will have a host called    host1
% Instead of creating a new subdomain under called sub, lets say
% that we place an A record in the zone file and name it host1.sub
% Now we have an FQDN of  which gives the appearance that
% a subdomain exists without really creating it.
% What I'm looking for is just some feedback on this practice. My thinking
% would be that you woudn't want to do this but I'd like to hear what the
% experts have to say about it.
% Thanks
