Oracle Weblogic IPv6 with Oracle database on IPv4

I have one weblogic application currently working on IPv4 and jdbc connection to database is on IPv4. Since my machine has an additional Ethernet port that supports IPv6, I am thinking to add an additional entry in DNS AAAA and try to clear my doubt. If an HTTP hit comes via IPv6 internally, weblogic will bind database on IPv4 and take the required results and give these results back to client browser on IPv6. - Will the above method work? - What are the other factors I should consider? - Is a dual stack mandatory other than IPv6 only?
