We have a system inside a DMZ managed by another organization. This DMZ is tightly managed, and any websites or other FQDNs must be explicitly defined as ones that our system needs to be able to access. A wildcard character is not allowed, so we can't use *.cisco.com . We need to make a list of something like www.cisco.com , ftp.cisco.com , community.cisco.com , the smart licensing site, etc.
