you have to use a name with A but no AAAA record for the test:
karme@amalthea:/$ dig -t A +short karme.de.
188.40.75.142
karme@amalthea:/$ dig -t AAAA +short karme.de.
karme@amalthea:/$ dig -t A +short www.gooogle.com.
173.194.69.94
karme@amalthea:/$ dig -t AAAA +short www.gooogle.com.
2a00:1450:4008:c01::5e

=> www.google.com. will not work
