Read an address nobody can dress up

Look at any web address and say, in about two seconds, whose machine it really is — however much of your bank’s name has been written into it.

Every web address has exactly one part that somebody had to buy, register and keep paying for. Everything else in it is free, and anybody may type anything they like there. Nearly every fake address in the world is built on that one fact.

Read the address from the left, and stop at the first single slash. Everything before that slash is the machine you are about to talk to. Everything after it is just a note to that machine about which page you want, and it proves nothing at all.

In fairbrookbank.com/accounts/login, the domain is fairbrookbank.com. In login.fairbrookbank.com, the domain is still fairbrookbank.com — login is a room inside a building the bank already owns. But in fairbrookbank.com.secure-signin.net, the domain is secure-signin.net, and your bank’s name is decoration painted on somebody else’s wall.

Key points

What to remember

Try this

Open any email from a company you genuinely deal with and hold one of its links down without pressing it. Read the address that appears, and find the last dot before the first slash. Do it three or four times and it stops being an exercise and becomes something you notice without trying.
