I note that looking up the mac address, it is a Buffalo Inc device.
IIRC some vendors (Cisco is an example which does who ought to know better) use 126.96.36.199 for their admin interfaces.
Searching buffalo and 188.8.131.52 on google lead me to believe buffalo use 184.108.40.206 for at least some of their devices.
Out of curiosity, can you access anything if you try to connect to 220.127.116.11.
Additionally, do you have any wireless access points or wireless range extenders? Some devices use 18.104.22.168 for dhcp relay.
