there are many ips: mc.hypixel.net (main) us.hypixel.net (US) proxy.hypixel.net (other proxy) and a lot of others as well
Here is what the above code is Doing:
1. It’s creating a list called ‘ips’
2. It’s adding the IP address ‘mc.hypixel.net’ to the list
3. It’s adding the IP address ‘us.hypixel.net’ to the list
4. It’s adding the IP address ‘proxy.hypixel.net’ to the list
You can add as many IP addresses to the list as you want.
