For the uninitiated, the joke is:

Each number should has a maximum value of 255.
It's not often you see IPv5
Sorry, that's my IP. I was trying something
In addition to what others have already posted, I suspect that this might be an attempt to evade spam/phishing filters that are looking for an IP address with a specific regular expression. Having a fake IP address that doesn’t match the traditional ^((25\[0-5]|(2\[0-4]|1\d|\[1-9]|)\d)\\.?\b){4}$ format might let this message slip through.
86.75.30.9
That cancer support line should buy this one also
I often assume this kind of thing is part of an effort to filter for idiots
If you know that's an invalid IP address, you're probably less likely to fall for the scam after the scammer has put the setup work in. So if they filter you out before a scammer has to spend any actual effort on you, that means more time they can spend scamming people who might be more likely to fall for it
That's why these things often have egregious spelling errors and other seemingly obvious red flags
Just because I know what a valid IP is doesn't mean I'm not an idiot 😎
Let's see you write a regex for one, then we'll decide.
Why would anyone want to do that when there are dozens on stackoverflow?
That's not the probability they are looking for.
I do believe that is confirmed canon.
It's possible in general, but I don't think that's what's going on specifically here; not many people read IP addresses in such detail to notice such things at first glance.
It’s exactly what is happening, they’re filtering out people who know what an IP address is and can contain so that they get fewer time wasters.
Movies and TV shows actually do it this way to prevent actual machines getting group hugged.
Like in that one X-Files episode, where the Lone Gunmen hack into an invalid IP.
It's also why there's usually bad spelling or grammar in those e-mails as well
Oh yeah, that’s the new hexadecimal IPV8
IPv4 was easy to remember. IPv6 made it very hard. This implies that IPv8 has to be base64 encoded.
Hello, I am apparently an idiot. What is wrong with that IP address that people can tell it's an immediate phishing scam?
IP addresses can't have segment numbers going over 255.
IPv5.
I think you mean IPV0x08
I try to avoid "this" style comments, but I genuinely don't know how else to respond to this one. It was hilarious. I literally (by which I actually mean "literally") laughed out loud.
wait what? I feel like I am left behind in the tech. I only know about ipv4 and ipv6 😭😭😭
They’re making a joke. The numbers in the IP are way too high for v4, but the format isn’t v6, so it’s a “new range” of v8.
Where's IPv7?
In the drawer right next to IPv5
at 192.512.512.10.0/42.
Jesus Christ, that’s Jason Bourne’s IP address!
I'm more surprised that it's a normal UA instead of something like AppleWebkit/Gecko/ChromeSafari 547.0
Your first mistake is sharing this email with everyone here
Please, do not share the button. It's gross.
Probably outer space
