IF ora_client_ip_address='192.168.0.30' AND ora_login_user='UPCLMAIN'
THEN
RAISE_APPLICATION_ERROR(-20001, 'You are not authorized to login into this machine UPCLDEV OR UPCLMAIN');
END IF;

hi Pankaj,
Try using this code
create or replace trigger ip_restrict
after logon on database
declare
v_user varchar2(30);
begin
select user into v_user from dual;
if v_user = 'USERNAME' then
if sys_context('USERENV','IP_ADDRESS') not in ('IPaddress 1 goes here ','IP address 2 goes here') then
raise_application_error (-20001,'Access restricted for this IP');
end if;
end if;
before that ensure that no DBA privilege exists for USERNAME
Thanks
SM
