I.P. Address Updates {#ip-addresses}
====================================

The legacy I.P. address for the Cybersource Batch Upload service will be replaced by two new I.P. addresses. We recommend that you use domain names instead of I.P. Addresses.  
The new addresses will take effect at these URLs and times:
