How to find index organized table I'm working on Oracle 11g database and I need to list all index-organized tables.
Is there a dba's view to query for that ?

Thanks
Here is the query you require:

SELECT TABLE_NAME 
FROM DBA_TABLES
WHERE IOT_TYPE IS NOT NULL; 


The documentation states:


  If this is an index-organized table, then IOT_TYPE is IOT,
  IOT_OVERFLOW, or IOT_MAPPING. If this is not an index-organized table,
  then IOT_TYPE is NULL.
