They need a /128.  But experience has shown that BGP participants *do*
filter, and as such, it was decided to go for a /32 in RIPE land.  ARIN
does /48s.

This is the way it is done.

BGP filters.

But hey, so what.  There are roughly 4 billion /32s - what do you gain 
by saving 10 /32s?  The number of routing table entries (which are a 
larger problem than "exhaustion of the available /32s") doesn't change.

At the time the policy was written, people thought that this way would
be better.  On the subject of root servers, people tend to be conservative.

OTOH, no policy that can't be changed if people think otherwise today.
