High ping on Japan server.

Hello I have a high ping on the Japan realm despite living close to it, even vpn can't help me. My internet provider asked me for an ip address to make a tracert. I tried to look in the forums first but didn't find anything. Then I tried to find it in a text file named "logs" and found it, but then I tried to find it again but this time it was different. So I have three questions 1: Can you give me the list of ip addresses for Japan server? I just don't understand how many of them and do I need to do a tracert for them all? 2: Do they change or do they stay the same? 3: Will POE 2 have the same servers and IP addresses as POE 1?
