If Each IPv6 Address Was a Second in Time

In an earlier post I offered some perspective on just how big the 128-bit IPv6 address space is. The ridiculousness of the number of addresses offers plenty of opportunity for levity. Earlier today I was thinking about what other ways I could show the size of the address space in a way that was meaningful. Time seemed like a perfectly normal way to try and gain some perspective. Here’s what I came up with:

Imagine each of the 340 undecillion IPv6 addresses (340,282,366,920,938,000,000,000,000,000,000,000,000) was a second of your day. If that were the case the total number of possible addresses would also be:

  • Minutes – 5,671,372,782,015,640,000,000,000,000,000,000,000
  • Hours – 94,522,879,700,260,700,000,000,000,000,000,000
  • Days – 3,938,453,320,844,200,000,000,000,000,000,000
  • Weeks – 562,636,188,692,028,000,000,000,000,000,000
  • Months – 140,659,047,173,007,000,000,000,000,000,000
  • Years – 11,721,587,264,417,200,000,000,000,000,000
  • Decades – 1,172,158,726,441,720,000,000,000,000,000
  • Centuries – 117,215,872,644,172,000,000,000,000,000
  • Millenia – 11,721,587,264,417,200,000,000,000,000

Oh well, those numbers are still too ridiculously huge to give any real perspective.  I guess the only thing they do is affirm that the address space is flippin’ huge!
