In late 2012, the company Dyn acquired TZO (Tzolkin Corporation), the sole DDNS provider that this NiagaraAX DDNS client was developed against. At the time of this document update, Dyn is not signing up any new accounts for the TZO service, although TZO servers may be working for existing accounts.Unless (or until) other DDNS provider options are available when using this platform configuration view, JACE controllers that require Internet connectivity using DDNS may be best served by installing on a LAN with a router capable of DDNS, and working through some other DDNS provider. The next update to this document will mention if related change have been made to this platform view.
