> For one thing, a /64 issued to a house is a pretty daunting search space for the scanning worms of yesterday. Some math to illustrate this: * IPv4 has 2^32 addresses * 2^32 ≈ 4 billion * in mathematics, a^x = a^(y+z) = a^y * a^z * so: 2^64 = 2^32 * 2^32 * therefore: 2^64 = four billion IPv4 Internets One IPv6 subnet can fit many, many entire IPv4 Internets. |
