Most likely there is a private address (in one of 10.0.0.0/8, 172.16.0.0/12,
or 192.168.0.0/16) being used there.  Tell the customer it is not their
router and to not worry about it.

Private addresses are often used this way.  There are complications to it,
and this is one of those.  But it is still commonly done for many links as
there is a huge supply of /30's in that space that can be used over and over
again in the net.  Only those engineers responsible for the router need access
to it, and they probably figured that out well before they decided to assign
such addresses.

There is a remote possibility it is filtered or just a very very old router.
