We are introducing a new charge for public IPv4 addresses. Effective February 1, 2024 there will be a charge of $0.005 per IP per hour for all public IPv4 addresses, whether attached to a service or not (there is already a charge for public IPv4 addresses you allocate in your account but don’t attach to […]
Hopefully this will ramp up the adoption of IPv6. See adoption graph here: https://www.google.com/intl/en/ipv6/statistics.html
Quick explanation of what IPv4 / IPv6 is written by ChatGPT:
IPv4 and IPv6 are both versions of the Internet Protocol (IP), which is essentially the internet's system for sending information. They're like the internet's version of a postal system, dictating how data should be packaged, addressed, transmitted, routed, and received at its destination.
IPv4 (Internet Protocol version 4): This is the older version, and it uses a series of four numbers separated by dots, like 192.168.0.1. The problem is, we've pretty much run out of unique combinations because there are only about 4.3 billion possible IPv4 addresses. That might sound like a lot, but with all the computers, smartphones, tablets, gaming systems, and other devices that need an IP address, we've run out.
IPv6 (Internet Protocol version 6): To solve the problem of running out of addresses, IPv6 was introduced. IPv6 addresses are longer and allow for many more unique addresses. An IPv6 address looks like this: 2001:0db8:85a3:0000:0000:8a2e:0370:7334. This means we're unlikely to run out of IPv6 addresses anytime soon.
In a nutshell, IPv4 and IPv6 are the systems that allow your devices to find and communicate with other devices on the internet. IPv6 is the newer, more advanced version that we're transitioning to because we've run out of unique IPv4 addresses.
