It wasn't [[https://github.com/wikimedia/mediawiki/commit/3db2a9156944330c9e9a9e8af28797f4539998a8|a mistake]] during abstraction so I don't know what it is and why it's tinyint(4).
Affected wikis to be altered in production by @Marostegui :
```
alter table ipblocks_restrictions change column ir_type ir_type tinyint(4) NOT NULL;
```
