EuroDNS EuroDynDNS

From what I have seen here

https://github.com/openwrt/packages/tree/master/net/ddns-scripts/files/usr/share/ddns

Apparently it is easy to support this one too. ( based on standard ddclient )

https://www.eurodns.com/dynamic-dns-documentation

I want to give it a try
Please tell me if I'm breaking something if

add a new name in
/usr/share/ddns/list

then I add a related file in
/usr/share/ddns/default/

By that documentation we need to have

https://update.eurodyndns.org/update/?hostname=%HOSTNAME%&myip=%NEW_IP%

what else I should take into account?
