What happens when we run out of IPv4 addresses? <- Can no more devices connect to the internet?
In: Technology
It just means organisations and ISP’s will only be able to buy blocks of IPv6 addresses.
The IPv4 in use will still be used, just their is a VERY limited number of IPv4’s available to buy. Companies sell back address blocks they don’t need, as well as those that go bust, so their will always be a handful of spare addresses around.
Day to day for us, their won’t be much of a change since we’re already using the IPv4 addresses. But we’ll see a transition by most ISP’s and Host providers to move users over to using IPv6 addresses and “retire” IPv4 to legacy equipment usage (i.e. old devices that can’t handle IPv6 addresses).
Running out of IPv4 does not mean the internet crashes to a halt. It just means their are none available to buy and we’ll have to use IPv6 as default.
