write as its value.
We first try country->iso_code which is the two-character ISO 3166-1
country code of the country where MaxMind believes the end user is
located. If there's no such key, we try registered_country->iso_code
which is the country in which the ISP has registered the IP address.
Without falling back to registered_country, we'd leave out all ranges
that MaxMind thinks belong to anonymous proxies, because those ranges
don't contain country but only registered_country. In short: let's
fill all A1 entries with what ARIN et. al think.
