As public dynamic DNS services declining from what they used to be a decade ago, it would be really of use to have in Yunohost app library a DDNS server app. Which could act as a hub for standard clients and provide users the update mechanism for their dynamic IP systems.
It would facilitate home decentralization: as people with static IP-addresses and VPSes could provide update their friends stable and reliable way to host their system at home. Moreover, people with Ynh at VPS will be able to utilize SBCes at home to have more private setups, or to implement services that aren’t present at Ynh.
If it’s not a place for such feature request, pls, help me to readdress it. Thank you!
