DNS Leak from Tsukuba only
Posted: Wed Dec 17, 2014 1:48 pm
I use the connection from this Japan operator (Tsukuba) a lot and its works well, but lately i found out that this operator VPN server is often blocked (used to be not blocked), so i google it and hit the topic of DNS leak. i perform the DNS leak testing from dnsleaktest.com and find that this server got dns leak problem.
i try to perform any kind of fix that i can found on google but it can not fix it, (flushing DNS, static IP, disabling DHCP). so i figure that the problem are on Tsukuba side, so i only can try to get this problem noticed by Tsukuba for now.
if there is something i miss please tell me, i will try any advice
note: i try to get other Japan operator, and they working well without problem
here some test result

What do the results of this test mean?
If you are connected to a VPN service and ANY of the servers listed above are not provided by the VPN service then you have a DNS leak and are choosing to trust the owners of the above servers with your private data.
if i`m on JP VPN i supposed to be on JP only (like the VPN by random PC owner on JP) not around the world, aside from that i not even in one of those country
