Browser displays site ip by default in javascript alertbox

Browser displays site ip by deafault in javascript alertbox. When i m displaying alertbox in login page in iphone application,it displays site ip by default and validation is done through java scrip开发者_运维问答t.

Most browsers use the hostname (or ip address if there isn't one) that they are accessing the site though in the title of any alert messages. This is a security feature so that users know exactly which site is responsible for the message (which protects against phishing).

Obviously, it can't be changed as that would render it insecure.

This is true mostly when you are developping on your local machine, it shows your IP, when you deploy it, or use it on the web it will display the host name. So users will know exactly which website is displaying the alert box.It is by default in place of alert box's title position..
