Geoblocking is the process of limiting user access to the internet based on their physical location. It is typically implemented by telecommunications companies, websites and other content providers and intellectual proprietors, often for the sake of copyright restrictions. Databases that map out IP addresses’ physical locations are often used to manage and enforce geoblocks.
Imagine you are traveling in Europe and you got some downtime and want to watch NetFlix. Chances are you won’t be able to use you Netflix account while abroad. This is because Netflix blocks access in countries outside yours, either due to licensing restrictions or geo political reasons.
Beyond content management and restrictions, Geo Blocking can be a great tool. For example; why would someone in, lets say China, need to access your home’s network? In most cases this would never need to happen, yet your router sees visitors trying to the “peek” in your firewall to see if there are any open “doors”, with Geo Blocking in place they would never be able to query your home network due to the country’s IP being blocked.
