Hi Everybody We are ISP in Japan to which IP 49/8 is allocated from JPNIC. It seems that it is set that IP that starts from 49/8 is refused on your website. (http://www.xbox.com) As APNIC has permitted us to allocate the customer IP 49/8 (Aug 2010), please remove IP 49/8 from the filtering No. list of your website. Please refer to the following for detailed information on 49/8 http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.xml
