Migration to Contabo from SeFlow – Nameserver and DNS

Hi to everybody,

I migrated from SeFlow, good service but awful support.

Only in the person of Matteo Berlonghi.

No professional skill, but I understood how works DNS world.

This is wants to be my personal diary.

Difference between Authority and Registrar.

usefull link to find which nameserver are registered to the Authority:

https://intodns.com/saic.it or http://mxtoolbox.com

in the DNS zone (NS record) you have to insert the nameserver that the Registrar sent to Authority.
