Google different IPs for different countries

Specs: N/A
How does google use different ips for different countries? By using just-ping, we can see that different ips actually used in different countries and the connection speeds are super fast. How can this be done? I've check and confirm that all the ips are from US, but how can the connection speeds be such fast in most of the countries? How do we know which ip is the fastest for a specific country if we are setting up a server?

Google uses IP addresses in exactly the same was as anuy other user on the Internet uses IP addresses.

Different users in different countries are allocated IP address by IANA The Internet Number & Naming Authority. Numbers are allocated in blocks to each country and each counter then allocated those numbers to individual users like ISPs, and companies.

The difference in speed you experience has nothing to do with IP address allocation, it is all down the the infrastructure that connects each country the Internet.

But if we use just-ping.com for other websites, It shows a great distinct for all the countries. This makes me a bit curious about their system. :)

It is not Google's system you should be concerned with, it is the Internet as a whole and they way that works. For instance there is around 200 individual pipes connecting the US with Europe shared by all Internet users, When connecting to a third world country there maybe only one or two pipes with a limited infrastructure which still has to be shared by all users.

Thanks, you'd reminded me that Google built their own fibre optic network... haha.
