Muy buenos días lista,<br>
<br>
Paso por aquí para compartirles el correo que está más abajo,
titulado: **"Weekly Global IPv6 Routing Table Summary"**.<br>
<br>
Como seguramente todos han notado, los días viernes llega a la
lista de LACNOG (y a muchas otras listas) un email con el mismo
nombre, pero sobre IPv4 (¡gracias, Phil!).<br>
<br>
Para hacer el cuento corto, desde finales del año pasado, unos
pasantes de la Universidad Central de Venezuela se pusieron a
trabajar en esta idea y, con el apoyo de VENOG y LACNIC, hoy podemos
decir que el proyecto es un éxito. El correo resume semanalmente
muchas estadísticas de IPv6 en la tabla BGP y, adicionalmente,
incluye un pequeño detalle por RIR. <br>
<br>
Y para ir cerrando, aquellos NOGs que estén interesados en recibir
este informe, no duden en avisarnos; con mucho gusto serán
agregados. Actualmente está automatizado para los días jueves pero
con mucho gusto se ajusta a la necesidad del solicitante.<br>
<br>
Reciban un fuerte abrazo,
<p><br>
</p>
<p>Alejandro,</p>
<p>P.D. Este trabajo no termina aquí, hay mucho más que puede/debe
ser añadido.</p>
