NOTE: Queries must be entered following the tradditionnal BIND format. For CNAME records, the 'dname' field must be under your fqdn. The 'data' field may be left empty, in which case the CNAME will point to your fqdn. In the case of MX records, only the 'data field is relevant since 'dname' must always be your fqdn. The format of an MX record 'data' field is 'priority host' where priority is an integer and host is the name of the mail router.
examples
a.myfqdn.ddts.net CNAME 'empty field' -- will result in a.myfqdn.ddts.net
pointing to myfqdn.ddts.net
b.myfqdn.ddts.net CNAME www.microsoft.com -- will result in b.myfqdn.ddts.net
pointing to myfqdn.ddts.net
'empty field' MX 0 myfqdn.ddts.net -- will make an MX record of priority zero
pointing to your own host. (NOTE: you most probably want to have such a field
to have mail routed to your main box before attempting other routes).
'empty field' MX 10 myfriend.hisdomain.com -- will make an MX of priority 10
pointing to your friend that routes your mail for you.
