I'm guessing that the following is happening: your router connects to your 
ISP, and gets two nameservers from there.  It uses one as it's own primary 
nameserver, and the second as a secondary nameserver, of course.  However, 
the router also serves names by proxy, so instead of simply passing those on 
to computers on the LAN, it replaces the primary NS with its OWN address.  
So, you see the IP of the router, and the IP of the secondary nameserver on 
your end.  In short, it looks fine to me.
