As I recall, at some point Internic was handing out subnets
of old class B space and reserving the remaining subnets for the same
organisation. If that's the case here then, 164.103.0.0/16
should be advertised sprintlink instead of 164.103.3.0/24.
Nice thought, except it doesn't work in practice.
We have 169.197.0/18. When we advertise it, Sean's
filters prevent ICM/ICP from getting it. When we
mis-advertise it as /16 the filter lets us through.
My two messages to INSC, 2 to engineer@sl, and 4 to Sean
didn't generate any solutions, so what makes you think
it will work for 164.103.3.0/24?
