Thank you for elaborating your concern, @qweasd. I'll point you in the right direction to get the network or IP addresses in QuickBooks Online (QBO).

To secure the network addresses, I suggest reaching out to the specialized Intuit Development Support team. They will assist you with the situation and offer you an appropriate solution, allowing you to move forward with posting a question on the Intuit Developer page.

Here's how:

1. Head to the Intuit Developer Community page.
2. Click Find a Forum.
3. Choose QuickBooks Online (QBO).
4. Click Ask a question.
5. Post your concerns and click on Ask.

I'm adding these articles you can use in the future:

• Update or change your Intuit Account sign-in information.
• Access and manage your personal data from your Intuit Account.

I'm always around the Community if you need additional assistance aside from accessing the network address. Stay safe!
