mysql granting access for same user from different hosts

[Ravi Malghan]

I have 3 client servers (host1, host2, host3) connecting to a MySQL database. All clients use the same username/passwd. Two of them will need all privileges. 3rd one needs only select privileges. Will I need to create 3 user accounts: user@host1, user@host2, user@host3, and 3 grant statements like the following. I donot want the user to be able to login from any others other than these hosts?

CREATE USER 'test'@'host1' IDENTIFIED BY 'ABC';
GRANT ALL PRIVILEGES ON *.* TO 'test'@'host1';
CREATE USER 'test'@'host2' IDENTIFIED BY 'ABC';
GRANT ALL PRIVILEGES ON *.* TO 'test'@'host2';
CREATE USER 'test'@'host3' IDENTIFIED BY 'ABC';
GRANT SELECT ON *.* TO 'test'@'host3';

or is there a way to create one account and 3 grants?
