Import partner IP addresses

Does anyone know if YNAB or the import partners make available the IP addresses used to connect to banks? Some of banks will notify me of new logins from IPs I don't recognize and while I'm forced to assume it's just Plaid/MX I'd love to verify that.

Other insights for verifying that would be helpful as well.

Also, I do recognize that if Plaid and the others were to publish the IPs they use it would make it much easier for antagonistic banks to block them, so if that's why I totally get it.
