YourIP.my was originally an experiment regarding the country code top level domains. Given it has the word "my" and my in English is used a lot, in a sense it is a backwards reverse domain hack. So in an algorithm is trying to decided if it has the word in it or not.
Granted this actually probably hurts the domain in overall world wide value though, as it is much harder for a domain from the country code of Malaysia to rank globally.
Thankfully the domain is only part of the entire project though, and I hope that you enjoy using YourIP.my and let your friends know about it. We have an API as well. If you have any questions, feel free to use the contact us link below.
