Doesn't matter.  Assuming we're talking about ARIN-region, if they're
multihomed, one of their providers can assign them a /24 (even if they'll
only use 2 IPs) so that they can announce that /24 to their other
providers and have a chance of not being route filtered.  ARIN rules
specifically permit this, and it won't be held against the provider when
they apply for more space.
