I need some help with adding values for the subdomain to assign to Marketing Cloud. It's probably very basic but I'm still getting familiar with DNS.
Using the domain sub.mycompany.com as example: in the example on the official documentation, only a part of subdomain is added:
But my IT says they need to be added like this:
sub.mycompany.com IN NS ns1.exactarget.com
sub.mycompany.com IN NS ns2.exactarget.com
sub.mycompany.com IN NS ns3.exactarget.com
sub.mycompany.com IN NS ns4.exactarget.com
Will this work or it has to be as shown in the documentation and some other examples I've seen?
