The body responsible for handing out IPv4 IP Addresses in Europe and the Middle East, RIPE NCC has today given an update on the expected final depletion of their stock of IPv4 internet addresses.
IPv4 internet address look like 18.104.22.168 and are an essential part of today’s internet. Every device on the internet needs to have an address so that other devices and services can communicate with it. The next generation address system, called IPv6, is slowly growing in adoption but there are still many devices that cannot communicate with devices using the new IPv6 address system. For that reason IPv4 addresses are still sought after, especially by new ISPs, who want to ensure their customers can access every system on the internet.
The update from RIPE NCC predicts that blocks of /22 IPV4 addresses will no longer be available from November 2019, just a month away at the time of writing this post. A /22 is 1,024 IPv4 addresses, and is typically considered the minimum routable size of a block.
Work-Arounds and Options
RIPE NCC still have a million IPv4 addresses available but not in continous 1024 blocks. So they will still help new entrants but they will get non-contigous ranges of IPv4 addresses. RIPE NCC also operate a waiting list – so if IPv4 addresses are handed back, they can be recycled for new ISPs.
Another option is the private market – IPv4 addresses are traded for-profit as they have now achieved a value due to scarcity. At the time of writing, a single IPv4 address is worth about $1.
IPv4 addresses are shared out amongst different geographical areas – some regions in the world have already run out, but some still have reserves – providers can set up local presence in a region that has reserves to obtain IPv4 address space.
Long Term Solution
The new address space, called IPv6, is the long term solution. In fact it is already adopted by all major internet service providers and content providers. So if you use a modern device, and visit the typical popular websites you could well be using IPv6 already and not know about it. But one day, if you are search for some obscure site or have decided to turn on an ancient computer, don’t be surprised if things don’t work like they used to….
As of 08-07-2019, the end of the first week, there were 40,284 registrations. Probably far short of what Nominet were hoping for. But good news for the “ordinary registrant” as there are now tens of thousands of new domains available for first-come, first-served registrations.
It’s not suitable for keeping two “live” accounts in sync, but for our purposes should be used, after the email has been pointed at our servers, and you need to ensure your old email is not lost when your old provider turns off the service.
The other option is simply to drag and drop folders in your desktop email software from the old account to the new account. This is perfectly fine but you do need to ensure you copy all the folders and don’t miss any.
