said by TomS_:So indeed a very odd thing, I would like to know more...
Ya
it was weird and when it happened I was like WTF.
IIRC it was on a 2651 router back around 2006 or so. (maybe a bit earlier)
I would guess they'd have to give themselves some funky rout that let them know of the hops from them to me then give a default route of my router.
But ya if I could find that site again I think I'd try to figure out how they were checking.
