nas.domain.com A    127.0.0.1 3600
nas.domain.com AAAA ::1       3600

• Find the IDs in the source code of the website. You can also use the element picker of Chrome / Firefox / etc. Its usually something like `record_div_XXXXXXXX". Take only the XXXXXXXX part.

Then, enter the IDs as well as your credentials in the dnsupdate script:

cd /root/inwx.de-ddns/
vim dnsupdate

• Run it as often as you want and in the Execute command area enter the following:

cd /root/inwx.de-ddns/ && bash dnsupdate

There you go. If you have questions, please create an issue.
