For me I open on webpage on my router. Drop the connection then connect again and I have new IP. It takes me seconds to do.
IP bans do nothing, as other have said, until everyone has a fixed IP. This might happen with IP6 but use of that is ages away if the sluggish move to IP6 is anything to go my.
Pointless the devs implementing a system. If you need it use in/out sim.
