I know that sprint and another ISP are having a disagreement about interconnections . I dont know if that is still going .  I havent had trouble with www.hogsoft.com though that should be an american address and the pricing seems to be english pounds .

195.8.78.1 is the ip address I get. You could try a ping from the command prompt that is on the accessories menu.  If that doesnt work try tracert and see where the block is , or just call your isp tech support.

ping www.hogsoft.com
tracert www.hogsoft.com
ping 195.6.78.1
