Phish, please help me consider why the Pentagon would want old "IPv4" addresses. I thought EVERYONE was going to IPv6.
Now, the truth is I'm not enough of a networker to truly grasp the real reasons we were all s'posed to go to IPv6. I thought we were just running out of IPv4. Was there a reason for moving to IPv6 that not many people knew? Anyway, I'll be digging with you. Happy sp'lunkin'!
Well, while the 4.3 billion potential IP addresses in IPv4 might seem like a lot, we need a lot more IP addresses.
There are a lot of people in the world with a lot of devices. This is an even larger issue with the rise of IoT devices (Internet of Things) and sensors, as these greatly expand the pool of connected devices.
Put simply, the world was running out of unique IPv4 addresses, which is the biggest reason why we needed IPv6.
The most obvious difference, and the most applicable for regular people, is the difference in formats:
IPv4 uses a 32-bit address
IPv6 uses a 128-address
IPv6 offers 1,028 times more addresses than IPv4, which essentially solves the “running out of addresses” problem (at least for the foreseeable future).
You are most gracious. And I DEEPLY appreciate the explanation. It is folks like you who - over and over again - make me especially grateful for the GA.WIN community.
I mean it as a compliment: "I hope I can learn from and carry on your example."
You give me the privilege of standing on tall shoulders.
I’m an average anon. So many here excel beyond what I provide. Each of us have individual strengths and knowledge, but when combined as a WHOLE we are POWERFUL!! ??
32bit vs 1028bit addresses doesn't mean the number of addresses that can be created, but the number of 'digits' in EACH address.
Consider street addresses - if you have a 2 digit street address, you can have 99 addresses on that street. As you add digits, the number of combinations goes up significantly! Same here. IPv4 has 32 bits in each address - giving us billions of combinations - while IPv6 has 1028 bits in each, opening up more combinations than there are stars in existence.
I am a network guy and the 20 or so ISP circuits with static IP addresses my company has bought in the past year have all been IPv4. Comcast, verizon, cogent, spectrum and Windstream throughout the USA
Thanks, Radian. That's really interesting. I realize there might be many reasons for preferring IPv4 and I never progressed far enough to understand much more than the IPv6 addresses were supposedly never going to run out. I guess I'm just hoping that the 'geeks' (mad respect for all of them) who enable the Military's control of all those addresses are 'white hats'. Time will tell.
THANK YOU for your gracious response! Thank you for being here! GBY & your loved ones! Working together, we MAGA!

The whole is greater than the sum of its parts.
Outstanding!
IPv6 has trillions of quadrillion of times more addresses, not 1028.
Well that’s the published data...I got it off a tech site.
He said 1028 times more or 1028x
32bit vs 1028bit addresses doesn't mean the number of addresses that can be created, but the number of 'digits' in EACH address.

You're kind of both right. -ish...
Interesting ??
