WARNING: This blog post will be semi-technical.
First and foremost, if you are using Windows XP, you need to upgrade. Mainstream support ended years ago, extended support ended months ago. The last release of XP was over 6 years ago. Really, just upgrade. Okay, on to the heart of the matter.
IP addresses are one of the core pillars of how the internet works. An IP address is used to locate a unique host on the internet, sort of like a phone number or a regular street address. The internet is running out of version 4 IP addresses (IPv4). There is a solution, version 6 IP addresses (IPv6), but there is issue if you are using Windows XP, your operating system only supports IPv4.
So with time ticking until we run out of IPv4 addresses, it’s getting harder and harder to get them. That presents another problem. Secure certificates. These things are what provide encryption on the web so you can securely transfer your private information, credit card numbers, etc. Often times, a browser will show a lock in the address bar along side the” https ” to show you that you are secure. You need a unique IP for every secure certificate, or you used to at least. There is a newer thing called Server Name Identification (SNI) where you don’t need an IP for every secure certificate, but again, XP does not support that, so it’s irrelevant.
What we are driving at is, Sephone is not likely to host new secure certificates that support Windows XP, they no longer support it, so neither can we. You need to upgrade. We will continue with the “grandfathered” ones we have, but it’s time to stop letting Windows XP keep all of us from using the proper technology to do the job. Do the job right.
