My localhost's IP address/port is being blocked from accessing a certain site. The blocking is occurring, but I don't know where.

The question is : does IP blocking possibly occur not only at the endpoint, but also at any intermediate server along the way?

Take a tracert, for example. Could the IP blocking be possibly occuring at any server whatsoever along the tracert path, or can the blocking only be done at the endpoints?
