BRACE YOURSELF, IPV6 IS COMING

Summary from the TLDR newsletter

AWS will start charging around $4 per month for IPv4 addresses on February 1. While IPv6 is clearly a good thing, there are still challenges to switching to it. The biggest challenge to global adoption is ISP support. A lot of developer tools aren't set up for IPv6 yet. If you want to ensure your company continues to run smoothly after February 1, start making as many changes as possible now.
