I don't think IN does what you think it does. It's not a substring-test,
but a set test:

SELECT 1 WHERE 'x' IN ('a','b','c','x');
SELECT a FROM foo WHERE b IN (SELECT z FROM bar WHERE frozzled<>wamble);

You could mess around with substring() and length() or I'd use LIKE.

If it's just a domain you're looking for though, might be most efficient
to strip the leading part off your value with regexp_replace().
