However, my intention in posting here is to connect with other users who might be experiencing similar issues and to share our experiences.
That is not where the forum is for either. These things have to be solved by ticket system.
And no, other users or sharing issues can -not- solve problems or find solutions. You have to obey the license agreement and other users can not unblock your ip's or licences in any way, so that is a non argument.
You were made aware of the fact
multiple times that tickets close automatically because legacy license have the lowest priority due to the fact that they have no ticket support and after a few days without reply they close automatically. You have to reopen your original ticket until you get an answer. Which you already had some time ago, I'm sure.
And also if you send mail via sales, you have to wait your turn.
But it won't help either way if you don't or can not provide the necessary proof, which you obviously can't.
You were also made aware in the ticket how to proove your case, because DA always do that.
You were also shown before by me and by the wayback machine, there you don't have any website selling servers with licenses, so that you don't have any right anymore to use these licenses.
DA never promised unlimited ip block changes for internal licenses, so in fact they can even lock them at the current ip's if they want anyway.
My frustration stems from the lack of response and support from DirectAdmin, and I appreciate any constructive help or advice from the community.
We all understand the frustration if you are really ligit, but you already had the appropriate advice from the community multiple times. So please don't keep asking the same every time.
Only ones able to help you is DA itself, not the community.
If you can't supply what they need, you are either using the internal licenses in an illegal way (not according to agreement) and maybe had to buy external licenses, or you have bad luck and the only solution is to sue them.
Wish you good luck with that as I'm sure the proof required should be easy to provide if it's legit.
Compare it to cPanel, if you can't proof that a netblock belongs to your ASN, it's end of story anyway. So it's not strange that DA is doing the same and they are not even as strict as cPanel.
Anyway nobody here can help you!
