I wrote it that way on the off-chance that additional special codes might be added in the future. For example if ?? were added to represent IPv6 addresses, they would be ignored by my rule, but /^(?:(?:GB|US|\*\*)\s?)+$/ would treat ?? as if it were a foreign country code. BTW does anyone know if there's a way to get the FreeBSD p5-IP-Country port to update its database. I just noticed it's nearly two years old.
