It is known that the numbers IPV4 is dwindling now
It then must shift to IPv6
Countdown to the end of the old version her

85 days of IPv4 remaining? What a load of bull.

There's no need to panic, of course, since you can buy what you need right on that page! ::)
Also, they fail at math... 2^32 (bits in IPV4 address) means there are
4,294,967,296 possible addresses (sans a couple hundred thousand or so for the reserved LAN addresses), which means that their 196,880,299 figure is not even close to that "maximum".

And I doubt there are 4.3 billion computers connected to the internet on different connections.

Actually, there are less than 4.3 billion public ip addresses available. Take out the whole ranges of 10.0.0.0, 127.0.0.0, 172.16.0.0, and 192.168.0.0 to get your number. And of course there are dozens of class A subnets that are reserved by iana and don't forget that large companies buy whole blocks of ip addresses and don't use them right away.
According to the iana website, there are only 7 class A ranges left unallocated. Once those are bought up, the big move to ipv6 will happen. Even though all the ip assignments aren't being currently used, once, they're assigned to someone, they're taken.

Either way, it doesn't matter how many are left, since you cannot just say "there are X days and we'll run out".

Just because address's are taken doesn't mean they are actually being used.
From Wikipedia.
Organizations that obtained IP addresses in the 1980s were often allocated far more addresses than they actually required, because the initial allocation method was inadequate to reflect reasonable usage. For example, large companies or universities were assigned class A address blocks with over 16 million IPv4 addresses each, because the next smaller allocation unit, a class B block with 65536 addresses, was too small for their intended deployments.

But it does mean that no one else can use them. Whether they're actually used or not doesn't make a difference.

Agreed. It is kind of silly. Kind of like arrival and departure times for airlines.
