Hi, I'm somewhat new to this new IPv6 format. I did search around Experts-Exchange, but am still somewhat confused. When this great change over happens, will I need to junk all the routers at my companies because they only have a choice of entering 4 numbers for the IP address, or will they (Linksys, I'm looking at you) release a patch? Or will the ISP's make this seamless? Also, will I need to change out my modems? Last one, do the clients care? I am assuming my internal LAN dosen't need to change as long as it's benind the router.
