This Phishing email... What is the IP?

Oh yeah, that’s the new hexadecimal IPV8
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.
Yeah, IPv4 addresses use four bytes. Those four bytes are represented as four decimal numbers, separated by dots. And a byte can only represent the decimal values 0–255.
Ahhhh. Thank you. Now the Ipv over 4 numbers make sense.
