...for example, the e-mail should say the IP address, the owner of the IP (based on a "whois" lookup) and the operating system that the user was on, and whether the login was successful or not. (The way that the message is worded, it sounds like the logins were successful, therefore, probably me! But this help article says that the feature is triggered for unsuccessful logins. Multiple unsuccessful logins should result in a message saying how many unsuccessful attempts there were.)
