The very basics

An IPv4 address is 32 bits long. An IPv6 address is 128 bits long.

What kind of difference is that?

as 32-bit addresses. 2**32 is 4294967296. Or about 4.3*10**9.

IPv6 has 128-bit addresses. 2**128 is 340282366920938463463374607431768211456. About 3.4 * 10**39. A lot bigger.

But what are 30 orders of magnitude between friends?
