Forwarding from A Record's IP Address
Solution 1:
It does not work, and that is excepted. Your current understanding on how DNS works is incorrect; you cannot "give an A record for the second time".
An A
record simply maps the name to an IP address (or multiple IP addresses for round-robin redundancy), and the DNS resolution is finished. It doesn't delegate control over the record to the server which it is pointing to – only an NS
record would do that.
