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 22.214.171.124 for their admin interfaces.
Searching buffalo and 126.96.36.199 on google lead me to believe buffalo use 188.8.131.52 for at least some of their devices.
Out of curiosity, can you access anything if you try to connect to 184.108.40.206.
Additionally, do you have any wireless access points or wireless range extenders? Some devices use 220.127.116.11 for dhcp relay.
