Not only for infrastructure, it will be used also to experiment the address delegation from IX to ISP's and direct attached
customers.

We will do some experimentation, but in principle we could follow /40 per country (nevertheless right now there is only a single IX
per country in our project), and /48 for each IX, and so on for ISP's (including the project participants), customers, ... But in
general, of course, we will like to plan multiples levels as much structured/hierarchical as possible.

We plan to announce only the pTLA from a single entity, as the project behaves as a single "entity" (or network or whatever you want
to call it). The pTLA will be announced by the entity who receives it in behalf of the complete project.

Anyway, in general, remember that this is a R&D project and we could try several approaches during the project life time, if it make
sense.
