Question: How does a company block access from an entire country? Is that done through DNS or IP range or something else?

>>Hardwa+Bj
When you receive a request to your website (or any service), that request comes from an IP address. There are databases that can tell you what country an IP address is from. It's not perfect, but it works well enough 99.99% of the time. Then, if the country is blacklisted, you do not allow access.

So that could be defeated by a VPN?

Trivially which is why VPN's have boomed in the UK since this was brought in.

An entirely predictable result given how easy it is to install a VPN vs having to verify yourself constantly to sketchy third parties on every site that has adult content (note: adult meaning adult not pornography..a lot of non-porn adult stuff get caught in the net).
