I would also love this feature, would mean i can get rid of a home-grade TP Link router on my network which does nothing but sync tplinkdns.com domain

@rtm42 

Read the user guide and there are four tpyes of DDNS providers are supported at this time. Tons of feedback on adding more and supporting more domain names instead of just one domain.

@rtm42 

Do you mean the built in DDNS service in the home router? Deco or Archer, I know they have such a domain you mentioned. Business class, nah. Never heard they have such service. You purchase plans from the 4 service providers. DynDNS, NO-IP etc.. 

yes, the tplinkdns domain syncing available on consumer grade stuff.

I see no reason why they cant implement this (its just a dynamic dns server after all) in their business class routers.

Its much neater for me to have that synced from primary router rather than having an old C6 with (almost everything) disabled on it sat on my network in a corner unnecessarily drawing power

I really dont see why i should pay for (or use a limited free service) that it has built in when ive been using the tplink dns for years.  i really dont fancy changing over 50 VPNs with a new hostname....
