Queries return results in psql shell, but not Django

Question

I'm trying to query a GeoIP database with the following schema:

CREATE TABLE api_geoiprecord
(
    start_ip inet PRIMARY KEY NOT NULL,
    end_ip inet NOT NULL,
    region VARCHAR(2),
    country VARCHAR(2),
    city VARCHAR(50),
    postal_code VARCHAR(50),
    latitude DOUBLE PRECISION,
    longitude DOUBLE PRECISION,
    dma_code INT,
    area_code INT
);

When I run this query in psql I get the result:

-- Test address, belongs to Yahoo!
SELECT city, country from api_geoiprecord
WHERE inet '68.180.194.242' BETWEEN start_ip AND end_ip
LIMIT 1;

   city    | country
-----------+---------
 Sunnyvale | CA
(1 row)

When I run it in Django I get nothing:

def get_location(ip) -> None:
    cur = connection.cursor()
    cur.execute(
        """SELECT city, country FROM api_geoiprecord
           WHERE inet %s BETWEEN start_ip AND end_ip
           LIMIT 1;""",
        (ip, )
    )
    return cur.fetchone()

Any thoughts?
