Consider every consumer gets a random PI-prefix out of the global unicast address space. Now you have two problems with a public PITR: 1. What prefixes does the public PITR have to announce? Where to get the list from? Scan all Map servers? 2. Billions of random PI-prefixes need millions or even billions of BGP-routes to be announced by the public PITR via BGP. If there's one dedicated EID address space a public PITR only has to announce ONE BGP-route to himself. Best regards, Renne
