Hello,\n\ncan anybody tell me what is the difference between \ncreating a subdomain or a delegation to a primary zone on \nthe same server ? What I mean is:\n\ndomain: example.com on server1 (primary zone)\n\n1) create subdomain "dev.example.com" on server1.\n2) create new primary zone "dev.example.com" on server1. \nCreate delegation under "example.com" on server1 that \npoints to itself. (windows does this automatically if I \ncreate a new zone that has the same root domain as a \nprimary zone)\n\nAs far as I understand, the only difference is that in \nthe second example I can replicate the domain and the \nsubdomain independently when using standard zone \ntransfers. What do you usually do in a production \nenvironent ?\n\nThank you.
