Since explicit CAST from INET6 to INT is prohibited, I would expect that this conversion would be too, or at least it should cause a typical truncation warning/error.
Same with TIMESTAMP, for example:
MariaDB [test]> create or replace table t1 (a inet6, b timestamp); |
Query OK, 0 rows affected (0.355 sec) |
|
|
MariaDB [test]> insert into t1 (a) values ('::'); |
Query OK, 1 row affected (0.045 sec)
|
|
|
MariaDB [test]> update t1 set b = a; |
Query OK, 1 row affected (0.032 sec)
|
Rows matched: 1 Changed: 1 Warnings: 0 |
|
|
MariaDB [test]> select * from t1; |
+------+---------------------+ |
| a | b |
|
+------+---------------------+ |
| :: | 0000-00-00 00:00:00 |
|
+------+---------------------+ |
1 row in set (0.001 sec) |
Can also be reproduced with ALTER:
MariaDB [test]> create or replace table t1 (a inet6); |
Query OK, 0 rows affected (0.321 sec) |
|
|
MariaDB [test]> insert into t1 (a) values ('::'); |
Query OK, 1 row affected (0.032 sec)
|
|
|
MariaDB [test]> alter table t1 modify a date; |
Query OK, 1 row affected (0.926 sec)
|
Records: 1 Duplicates: 0 Warnings: 0

|
MariaDB [test]> select * from t1; |

etc.
