getting traffic from an xurl redirect what is it?

I have no idea where this traffic is coming from but i am getting alot of it. Weird thing is the traffic from this url have a longer on site time then normal so I think its odd and i just have a bad feeling in my gut about it.

i cannot post a link yet to show an example but here is how it looks broken into 3 parts

63.223.106.16/xurl?=ttp//63.223.106.16

/9V83tvND8d7m9cC8cfff954dde6e42d699f03af81552659a36c&xref=

then an htp:// with my url at the end

i had to switch the http to htp to be able to post, thanks in advance for any help.

It also seems odd that around the same time this traffic showed up my clickbank earnings have fallen on this site to almost nothing

anybody?
