Amazon EC2: force.com pull IP
Hi,
I'm curious how people is configuring group permissions for EC2 instance services to be pulled from salesforce.com apps, since ec2 group permissions require a CIDR ip mask to explicitly grant firewall permissions, and i'm not sure how to obtain if a reliable static ip exists for the salesforce.com side, and how to obtain it

The purpose of whitelisting an IP address range is to allow for disaster recovery procedures with the Mirrorforce data backup centers and for future expansion.
There is no risk in white listing the specified range of IP addresses as Salesforce.com *OWNS* the range. It is not leased or shared in any way with any other organizations.
Salesforce.com moved from an IP address block sub-allocated by an ISP to a new address block allocated directly to salesforce.com by the American Registry for Internet Numbers (ARIN).
Salesforce.com strives to provide our customers with the best service possible. The MirrorForce data centers installations on the East and West Coast provide near real-time data replication and failover. Direct IP allocations make that possible.
In addition, direct IP allocations provide for:
-ISP Peering: The ability to select diverse peering to avoid congested networks.
-ISP Redundancy: The ability to easily expand beyond two network carriers
-IP Stability: The ability to maintain the same IP addresses with different network carriers.
The IP address spaces are as follows:
204.14.232.0/25 East Coast Data Center (set one)
204.14.233.0/25 East Coast Data Center (set two)
204.14.234.0/25 West Coast Data Center (set one)
204.14.235.0/25 West Coast Data Center (set two)
To clarify, the "0/25" that you see in the ranges does not refer to "0 - 25" or 26 IP addresses. It is network administration nomenclature which refers to the range of IP addresses from "0 - 127", so there is a total of 512 IP addresses.
