My router (Fritz!Box) by default connected to DNS of provider Telekom. Then any subdomain of dvl.to was not resolved (website nit reachable); ping neither works :
ping: contao413.dvl.to: Zu diesem Hostnamen gehört keine Adresse
DNS lookup via webservice (webservice) works well.
So I guessed that the newly created dvl.to was filtered out by the provider.
I therefore changed DNS Server setting in my router to cloudfare 18.104.22.168 , checked here:
So, my computer can connect to 22.214.171.124 .
Nethertheless, contao413.dvl.to is not resolved yet, nor does ping work.
All recommended tests worked well (f.i. dig contao413.dvl.to @126.96.36.199 ), but dig contao413.dvl.to brings no answer.
Not sure whats wrong; maybe the provider still blocks this tld? No way to ask them ;-((
