dev.mac/xcode/company name selection for xcode

6.7: proj.addn/dev.mac/xcode/company name selection:
. each developer needs a name,
and uniqueness depends on a co using their co`url;
what should I use as a company name ?
. is addx reserved at g'code? yes: http://code.google.com/p/addx/
so, when I actually get some code in a repository,
it will be at https://addx.googlecode.com/
and the name for mac will be com.googlecode.addx .
