如何从WordPress中的functions.php执行SELECT

I have had a google about and found a few posts but not a full answer. I want to run my own query when a page is loaded into WordPress. I want to run this query from functions.php:

function performSelect() {
global $wpdb;
$result = $wpdb->query("SELECT ip_address FROM MyTABLE ORDER BY datetime DESC LIMIT 0,1"); 

print_r( $result);

}

I get a '1' outputting on my page. How do I go about getting ip_address back as an actual field? I have ran the query on the server and it does return an IP, not a 1 as in WordPress!

UPDATE 1

I have now have this working, but I'd like to put in a loop for queries that return more than one row:

$result = $wpdb->get_row("SELECT ip_address FROM MyTABLE ORDER BY datetime DESC LIMIT 0,1", ARRAY_A); 

echo $result['ip_address']; // WORKS

How would I go about looping through $result? I've tried a few methods and all error.

    foreach($result as $row) {
        echo 'Ip address:'.$row->ip_address;
    }
