I'm curious though about why you'd want to change your IP address. Get banned some where?
You can change it, I always change my IP via Mac Address - but as the question specifies it's for someone else.. she keeps getting DDoSed from kids that think it's cool and it's starting to piss me off. I can't even watch the livestreams as everytime she streams they kick her offline, and in her case she has a router built into the ISP's modem.
I myself always had a router, and a modem two different units; not built into eachother, so i'm not familiar with the router/modem combo which is why i'm asking if you can still config it like that, but the guy above answered my question that it's dependent on the ISP and how they set it.
