GeoIP is PHP module. There is nothing wrong with using what's out there already coded for the framework/language XC is built on. It is actually something you better do - why reinvent the wheel in this. case. But the GeoIP applies to XC4 only.
XC5 uses the GeoLocation module which is another XC5 module based on data provided by MaxMind. So in this case the Module A/B remark can be used.
