IP address

 I want to know IP address.

My database(ASM) version is 10.2.0.5 on aix(2 node RAC)

I given the following

SQL>ALTER SYSTEM SET audit_trail=DB_EXTENDED SCOPE=SPFILE;

SQL>shutdown immediate;

SQL>startup

SQL>show parameter audit_trail

O/P: DB_EXTENDED

SQL>audit all on schemaname.tablename by access;

From sys.aud$ table, what information we can get, can we get IP address?

Is it enough to know IP address of the person who is doing DML operations on that table?
