[lacnog] Duda real capacidad direccionamiento IPv4

Jue Nov 13 19:24:47 BRST 2014

Haciendo un ejercicio en una tabla de cálculos las direcciones de IPv6
(2^128) es de  39 dígitos decimales o 36 dígitos después del 340, como se
muestra a continuación:

340,282,366,920,938,000,000,000,000,000,000,000,000

También, 340 se puede expresar en escala corta como undecillones o escala
larga como 340 sextillones y en escala binaria como 340 epicbits.
