Using an IP to Hex Converter in Cross-browser Testing
An IP to hex converter can be useful if you're doing cross-browser testing. For example, if you have a HTML form that accepts an IP address, then the JavaScript code that checks if an IP is valid might only check the decimal form (such as 127.0.0.1). However, IP addresses can also be written in hexadecimal form (such as 0x7f000001 and 7f.00.00.01). If you ping 0x7f000001 or 7f.00.00.01, you'll see it pings 127.0.0.1. With this program, you can create tests that compare IP addresses in decimal format with IP addresses in the hex format. Additionally, if you need to bypass someone else's IP checkers, then you can use this utility to quickly get hex IP addresses.
