Bringing your own IP address (BYOIP) can offer several advantages. Here are a few reasons why you might consider bringing your own IP address:
Improved security. Bringing your own IP address can enhance security measures. You may implement a firewall based on your own ASN and IP ranges.
Seamless migration and scalability. By using the same IP address, you can minimize the need for reconfiguration of your services.
Reputation management. You have the ability to manage your IP reputation, which can impact email deliverability, online reputation, etc.
Subscription management. Online subscriptions such as JSTOR often use IP-based access control to manage and restrict access to their content.
