Hi Göstha,
Maybe they just assume everyone knows.
Either way, it is never necessary to use more than one
Dynamic DNS from any one location, except maybe as a backup. I usually just enter one in my
router and never bother with any further devices, e.g. Webswitch, RRC, Webcam, etc. Only the
port numbers point to which device you want to access.
