They need to add more tubes to the series!
Bad news for current Mozilla users.
IT budgets are going to rise on this news!
Those with existing networks may have more problems with equipment, but what we are doing is all new, and I've spec'ed the correct equipment. I'm just glad I'm no longer maintaining a (soon-to-be) legacy network.

Why? Mozilla implemented IPv6 in 2000.
Would someone please logoff, I need to check my email!
Good cover for surfing pron.
Um, I need to, check my email too! In private!
LOL!
All the way back in 1991, when I first started using the internet, I was astonished that there were so few IP addresses. I honestly don’t understand how the heck anyone engaged in planning for the future could, at that time, allocate fewer digits than the number of people in the world. By 1997, when I was working in a single lab where there were on the order of 3 computers for every employee, all networked together, I realized with certainty the situation had to be addressed rather soon. About that time, even our utility providers had assigned unique IPs to various equipment that was connected to the home office.
I am somewhat concerned that IPv6 (which I think is 2^16, ~65,000, more addresses than current) will prove insufficient, and that instead we should be going to an IPv8 configuration instead.

Read and digest article!
The first thing to do with any new install of Firefox is to about:config and disable IPv6.
It's a problem that's most noticeable in Linux.
My assumption is that they're addressing it in 4 because I never disabled IPv6 in my builds of that, and they're running as well as when it's disabled in previous versions.
There is an easy way to encouage businesses to give up addresses that they are sitting on. Start charging $.01 per address annually. I suspect that many firms that are sitting on litterally millions of addresses will start to rethink that policy and turn more address space back.
Further, if IPv6 is left as free, then there will be new drive to make the move and convert. This will in turn free up more address space.
Another move would be to make the local host address 255.0.0.1 instead of 127.0.0.0. Likewise the local network would be 255.0.0.2 - 255.255.254.0 - .255
It’s not that bad. There are public and private IPs. Many public IPs are used on corporate or other managed networks. A gateway plus the use of Network Address Translation (NAT) can convert many of the public IPs to private IPs. This frees up a substantial percentage of the public IPs. Many intranets already do this when they’re running out of their public IPs.
Chances are if you’re on a cable modem you’re NAT-ed to private IP space.
Most mid-level network engineers know how to do implement the conversion.
Turns out that the original addresses were for the ARPA development, and no-one knew that the internet was coming, or would be world-wide.
So the orginal addressing space was plenty for the military testing that was contemplated.

The company I work for, we use a 10.x.x.x subnet which is local. My previous company, we used actual real IP numbers but they were not accessible from the outside but they could go to a local IP like 10.x.x.x, 192.168.x.x and forgot the other one. I know companies like HP have a block where it is Class A -> 4.x.x.x. Those who still have Class A’s should be encouraged to give them up.
Are you serious? When IP was developed, in the 60’s, there was ‘plenty to go around’. No one envisioned half the planet carrying phones that have distinct IP addresses.
Of course, my phone doesn’t need a publicly routed IP address - it needs a PRIVATE address on my carriers network, that goes through a NAT pool to reach whatever site I want/need.
Additionally, IPv6 allows for a number (even larger than the US national debt!) that is rather unimaginable. It’s roughly 340,282,366,920,938,000,000,000,000,000,000,000,000 IP addresses. Divide that by 6,500,000,000, and you’ve got 5,235,113,337,245,200,000,000 per PERSON. I don’t have that many devices that are IP capable, and I work as a network architect at a university. IPv6 will be sufficient (and then some).
IPv6 is 2^128. It’s a truly astounding number of addresses.
