I asked Merit about this last year.  Apparently it thinks any announcement
between a /25 and /32 is a "host" announcement.

As far as I know no IP registry has issued any address longer than a /24
split between more than one organization.  Given that both 128.88.250.0/27 and
128.88.250.32/29 are being announced by the identical ASN and identical
upstreams, perhaps they could aggregate it into a single announcement.
