Long story short: After this week’s switchover to a new protocol called IPv6, there are a whole lot of IP addresses on the Internet.

How many more?

Just one day after the world wide web made a permanent and forever change on Wednesday, CNN reported the Internet now has 340 trillion trillion trillion unique addresses. That’s 340 undecillion.

We knew the switch from IPv4 to IPv6 would make a bunch of new addresses available. But this is a growth of 79 octillion (billion billion billion), according to the report.

But we have no frames of reference for a number that large, so let’s put it into context for a moment.

Holy crap!

I don't know if I can believe that. Given the fact that man has never explored the universe in its entirety, saying there are more net addresses than stars is extremely premature.

What Dexter said. We should say that we have more addresses than KNOWN stars in the universe. Not to mention the fact that the universe is constantly expanding.

They're all estimations, there's obviously no way to know exactly how many stars there are in the entire Universe as its dimension still remains unknown.

When scientists previously estimated the total number of stars, they assumed that all galaxies had the same ratio of dwarf stars as the Milky Way, which is spiral-shaped. Much of our understanding of the universe is based on observations made inside our own galaxy and then extrapolated to other galaxies.

But about one-third of the galaxies in the universe are elliptical, not spiral, and van Dokkum found they aren't really made up the same way as ours. Using the Keck telescope in Hawaii, van Dokkum and a colleague gazed into eight distant, elliptical galaxies and looked at their hard-to-differentiate light signatures. The scientists calculated that elliptical galaxies have more red dwarf stars than predicted. A lot more.

Generally scientists believe there are 100 billion to a trillion galaxies in the universe. And each galaxy – the Milky Way included – was thought to have 100 billion to a trillion stars. Sagan, the Cornell University scientist and best-selling author who was often impersonated by comedians as saying "billions and billions," usually said there were 100 billion galaxies, each with 100 billion stars.

Van Dokkum's work takes these numbers and adjusts them. That's because some of those galaxies – the elliptical ones, which account for about a third of all galaxies – have as many as 1 trillion to 10 trillion stars, not a measly 100 billion. When van Dokkum and Conroy crunched the incredibly big numbers, they found that it tripled the estimate of stars in the universe from 100 sextillion to 300 sextillion.

Van Dokkum's paper challenges the assumption of "a more orderly universe" and gives credence to "the idea that the universe is more complicated than we think," Ellis said. "It's a little alarmist."

That's insane and as said above, there's no way to know how accurate that is.
We don't know how many stars are in the Universe.
However, the number of IP adresses is acurate in the way they described it in numbers.
It's almost unbelievable.

That's freaking crazy. I knew there was a lot of people/addresses on the internet, but I didn't think there was that many!
