Updating IP Address For GDP

Dear Instructors,

Our content delivery network provider has added a new range of IP addresses that our GDP content can be delivered through.  This means that there are more servers providing access to GDP, further increasing reliability and service.  Please have your IT administrator allow access to the new IP range highlighted below and verify that the existing ones are also in the system.

CIDR Notation CIDR Address Range
69.28.128.0/18 69.28.128.0 – 69.28.191.255
68.142.64.0/18 68.142.64.0 – 68.142.127.255
208.111.128.0/18 208.111.128.0 – 208.111.191.255
