Hello Stig,
Thank you for the question.
Server Domain depends what server you want your device sending the data to? Do you have your own server? Are you planning to rent teltonika server or a thirdparty one?
If you already bought let's say TAVL4 services from teltonika, then it depends on what server your device is registered on. Regarding your question about the tracking - yes, you can view vehicle tracking on the computer via application or web.
Unfortunately, we can't publicly give the license key on the forum, I would direct you to your sales manager about these questions.
If you have any further questions don't hesitate to ask. Alternatively, upvote the answer if it provided a solution to your question.
Stay awesome and have a great day. :)
Best regards,
Vytenis
