A /28 SWIP only works for the name of the ip addresses, not the
nameservers. The parent ip space would still be listed and the rDNS
would have to be delegated from the provider nameserver.

Persistant complainants will always CC the upstream of the ip space
anyway.

A /24 would be better as you could shield the upstream a tiny bit more.

Multi/anycast, at least using BGP, require the assistance of the ISP.
