This Phishing email... What is the IP?

Oh yeah, that’s the new hexadecimal IPV8
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
