Detailed setup instructions for a wide variety of OSs

Difficult to use on some routers and NVRs

Routers and NVRs that give you set options (that don't include Duck DNS) won't work with Duck DNS. Apparently Duck DNS claims they support DynDNS or something of the sort, but the information it gives you, there's nowhere to plug it in in these boxes. See More
