That is a link local address and harmless.

Check for a line starting with "default" - you should not have that.
However, the fe80::1 probably points at your router, claiming to
be a IPv6 router, which it isn't (if as you say IPv6 is disabled).

A router that offers a route but then doesn't properly forward IPv6
packets is broken and should be fixed.
