1) Using what protocol?

2) As John Brown mentions, do a tracroute to that IP from your 
location.  My views show that the address you list is not in the 
global BGP tables.  Spoofed single packets might hit your machines, 
but they have no way of getting back unless your local routers have 
static or locally learned routes to that destination.

In short: don't worry about it, probably.
