IEPL
IEPL usually refers to an international Ethernet private line. With this route type, part of the international transmission uses a managed private link, reducing reliance on changes to public internet routing along that segment. Other network segments remain between your client and the entry point, and between the exit and the target service, so an IEPL label is not an end-to-end quality guarantee.
A useful option for tasks that depend on a sustained connection, such as remote work, longer file transfers or video calls. If public routes fluctuate at the times you usually connect, compare them with an IEPL route and test your actual apps rather than relying on the connection status alone.
Dedicated transmission generally involves higher procurement and maintenance costs. This is a general aspect of network infrastructure, not a separate charge by X4VPN for any particular route. Check your subscription and user dashboard for current options.
