Domain masking

Domain masking or URL masking is the act of hiding the actual domain name of a website from the URL field of a user's web browser in favor of another name. There are many ways to do this, including the following examples.
Once the URL is masked it displays the URL mask rather than the original URL/domain name. Masking does not affect the content of the actual website; it only covers up the original URL/domain name. Domain masking prevents users from being able to see the actual domain website, whether it be due to length or privacy/security issues.
