Should I use my Dynamic IP or the gateway address for a Custom IP?

Please note that we have been using Akamai DEEM (dynamic encoder to entry-point mapping) approach for the selection of the publishing point for several months.

This new approach provides improved throughput and automatically optimizes entry-points based on current Internet conditions. Therefore, there is no more the possibility to select a publishing point in the new back office because Akamai automatically optimizes it for you to ensure a high quality ingest.
