Price remains pretty constant so there does not seem to be any demand issues influencing the price of IP addresses. In fact, Azure price seems to have moved down slightly, over and above my mistake in using Azure's default 730 hour month calculation last time (there are no months with 730 hours in them, that I know of).
Perhaps this is the new, metric February we've been hearing so much about. :)
I think it is time to seriously look at the issues with security and factor that into the equation. Will be creating a blog post on this topic in the coming weeks.
A few years ago I saw an article about IP v4 addresses and how IoT was causing us to run out of them quickly. At the time it seemed odd, because I knew that you could get them for nothing, or next to nothing, from every cloud provider.
If we were really running out, wouldn't you expect to pay something for them? Wouldn't supply and demand dictate that they couldn't be given away for free?
But perhaps this is really starting to happen now.
I just received an email from Google Cloud that, perhaps, There's No Such Thing as a Free IP Address Either (TNSTAAFIAE).
From the email:
First, we’re increasing the price for Google Compute Engine (GCE) VMs that use external IP addresses. Beginning January 1, 2020, a standard GCE instance using an external IP address will cost an additional $0.004/hr and a preemptible GCE instance using an external IP address will cost an additional $0.002/hr.
In addition, there are also price increases at Azure, though not in the classic resource deployment mode.
Here are the spot prices today for single static IP addresses (based on a 30 day month):
