Hola, lista, muy buenos días/tardes,
Primero, agradezco enormemente los mensajes de la semana pasada apoyando
esta iniciativa. Parece algo muy sencillo, pero aquellos que han
trabajado con tablas BGP saben que no es así. :-)
Si todo sale bien, este reporte llegará de manera semanal,
específicamente los días jueves. En unos meses, se podrán hacer estudios
muy interesantes, como gráficar cambios de algunos valores (ya tenemos
algo en IPv4 [1][2]) y agregar otros ítems, como el factor de
desagregación y RPKI. Bueno, en fin, es mucho lo que se puede añadir.
Muy pronto quedará disponible en GitHub también.
Reciban un saludo y se aceptan quejas, sugerencias y comentarios sobre
el reporte.
Fuerte abrazo,
Alejandro,
