Welcome back. API works perfectly but if you don't like getting API links each month/maintenance there is a method (http://kancolle.wikia.com/wiki/Tutorial:_Proxy_Connection#Option_3:_Editing_DMM_Cookie.27s_Region_Flag) that lets you play without getting new APIs. I myself have been playing with it for a month and didn't have any problem, also I didn't have to use VPN at all. So if it's the VPN use that is stopping you to play I recommend you that method.

About the second question, I think it's okay if you use the same IP but remember do not open the game at the same time.
