URLs can be obscured at least three ways to avoid recognition of a linked address for several reasons. An URL might consists of meaningless or deceptive text after "https://" and before an "@" symbol. The domain name can be expressed as an IP address, in dotted-decimal, dword, octal or hexadecimal format, and all of these formats have variants. Characters in the URL can expressed as hexadecimal (base 16) numbers.
You can easily add the URL de-obfuscator widget on your website by copying the following HTML code and place it on your web page
<div style="text-align:center">
<form action="https://www.ipaddressguide.com/url" method="post">
<p style="background:#fff;border:1px solid #99A8AE;width:180px;padding:5px 5px 5px 5px;font-size:11px;font-family:'Trebuchet MS',Arial,Sans-serif;">
