IP address of servers


I have big troubles with LAG, I thik is network performance from my ISP but I not sure. All other webpages works fine, also Youtube. But in discord I have some loss of voice and in game I have lag … its like keeps freeze for 2 or 5 secs and this is incredible annoying (especially when you go for a boar)

So, for a best troubleshooting I need to know the IP address or FQDN of servers. Can anyone help me with this?

Thanks in advance.
