Fetch array elements

Hello,

Is it possible to get a single element returned by function
REGEXP_SUBSTRING_ARRAY?

SELECT IP,
CARDINALITY(REGEXP_SUBSTRING_ARRAY( IP, '\d+')) AS "CARDINALITY"
FROM IP_LOG

For any valid IPv4 address, the above query returns 4. I'd like to
access the 1st, second, third or 4th element in SQL.

Thanks,
Andreas
