SQL & PL/SQL :: ORA-24248 - XML DB Extensible Security Not Installed?

When i try to gather server information by running the below query , i get error.

SQL>
SQL> select utl_inaddr.get_host_address ('Hostnamename') from dual;
select utl_inaddr.get_host_address ('Hostnamename') from dual
*
ERROR at line 1:
ORA-24248: XML DB extensible security not installed
ORA-06512: at "SYS.UTL_INADDR", line 19
ORA-06512: at "SYS.UTL_INADDR", line 40
ORA-06512: at line 1

I ran below query to see what is installed.

SQL>
SQL> select comp_name from dba_registry;

COMP_NAME
-----------------------------------------
Oracle Database Catalog Views
Oracle Database Packages and Types
Oracle Real Application Clusters

My question is do i need to install XML database to resolve this issue and is SYS user is required to perform this install?
