URLConvert will convert an IP address into a longer, numeric address with no dots (called "DWORD" format). It can also convert either an IP address OR a domain name into hexadecimal format, for example, phplabs.com becomes %70%68%70%6C%61%62%73%2E% 63%6F%6D You can use this capability to bypass some content filters and also to prevent your network administrators from knowing the real URLs youre visiting. As far as we know this form of url encoding works with every browser type out there.
