Many subscribers don't know what an IP address is, and don't care. I'm trying to imagine my parents receiving such a letter "renumber your IP address and/or buy a new PC or router". Such a letter would probably cause anger and confusion and an increased readiness to switch to the ISP across town that's using squat space and doesn't require customers to call Geek Squad or buy something else.
