Hola! <br>
<br>
Relacionado un poco con las conversaciones sobre gobernanza de
Internet que tuvimos en la lista hace un tiempo, les reenvio un
anuncio de ARIN (el registro regional de direcciones de America del
Norte) por el cual van a devolver una cantidad importante de espacio
IPv4 a IANA (el registro central del cual los registros regionales
recibimos espacio). <br>
<br>
Por razones históricas, ARIN es el registro que mas espacio legado
tiene y el que mas capacidad de hacer devoluciones de este tipo. <br>
<br>
El espacio devuelto es mas o menos equivalente a un /8 (~16 millones
de direcciones), pero como veran mas abajo, esta bastante
fragmentado, por lo cual no esta claro como va a ser la mejor manera
de usarlo. <br>
<br>
No pude dejar de notar que dentro del espacio devuelto hay unos
primos del bloque de SECIU, dentro de la 164/8 :-)<br>

Given the recent ICANN Board adoption of Global Policy
Proposal-IPv4–2011, the ARIN Board of Trustees at its 6 June meeting
directed ARIN staff to return to the IANA the IPv4 address blocks that
have been voluntarily returned to ARIN in recent years. The total amount
of space being returned to the IANA amounts to roughly a /8 equivalent
and includes the large block of IPv4 addresses returned to ARIN by
Interop in 2010.
Below is the final list of address space that has been returned to the
IANA and this will be reflected in ARIN's database within the next few
hours.
