A readable name, rented rather than bought, pointing at a numbered address. Look-alike names are the whole basis of phishing, so read them letter by letter.
The drawing that proves the sentence above. It is the same card that is in the book.

Volume 1 has all 275 in fifteen chapters, with Staying Safe the largest chapter on purpose.
