Some ISPs or service providers may use private IPs (RFC1918) or even APIPA for their internal routers, to spare public IPs.
CG-NAT (which uses APIPAs) especially may create some weird problems.
I think it's just a coincidence that the provider uses 192.168.0.2 internally and the OP host has the same address in its network.
