that depends...if it is really just the city name like boston.com or something like cityofsandiego.com
Foreign city names are tricky, there are hundreds of cities in China and India with more than half a million people, most of them nobody even knows here, no big value, also because foreign city names are most of the time written differently in the native language and in other languages. It would really only make sense if you post the name if you own it.
