Yeah I was lazy with saying ipv32 just to mean something excessively long. I didnt want to say ipv6, since I kinda think it needs to at least be 64bits (edit: ipv6 is actually 128bits), and really for a public-private key pair it should be larger, so more like 512 to avoid anything like the v4 v6 cacatestrophe again in 20 years with post quantum forms of asymetric key challenges. But I didnt feel like writing all that out.
I’m with you. I knew I’d get people not reading and say “that’s the ip address”, but MAC address? 🤦♂️
