How a website is placed in Czech Republic's list: by the main country MarketXY computes for it - the country of its country-code domain (such as .in or .de) when it has one, otherwise the country its page tags, language, registrant or hosting point to. A global brand can therefore appear under a country that is not its home market. US government and military domains (.gov, .mil) are not listed under other countries.
Not available right now: network operators, IP / ASN, hosting providers. These are read live and appear on the next visit.
