Selecting IPv4 value from IPv6 column returns an empty resultset

According to documentation, IPv6 supports IPv4 values as well. Inserting both values works just fine, but selecting IPv4 value returns an empty result set.

Example:

drizzle> describe ipaddress_table;
+-------+------+------+---------+-----------------+-----------+
| Field | Type | Null | Default | Default_is_NULL | On_Update |
+-------+------+------+---------+-----------------+-----------+
| addr | IPV6 | YES | | YES | |
+-------+------+------+---------+-----------------+-----------+
1 row in set (0.001061 sec)

drizzle> insert into ipaddress_table values ('10.28.4.10');
Query OK, 1 row affected (0.009366 sec)

drizzle> select * from ipaddress_table;
+-----------------------------------------+
| addr |
+-----------------------------------------+
| 000:000:000:000:000:000:010.028.004.010 |
+-----------------------------------------+
1 row in set (0.000795 sec)

drizzle> select * from ipaddress_table where addr='10.28.4.10';
Empty set (0.000814 sec)
