By public, AWS means the IPs NOT used by Amazon itself. The ips it assigns for its Cloud services are their Public IPs, not public in that anybody can use them but Public in that they are used by subscribers to Amazon cloud services. I think.

That make sense to you?

Because they have many subscribers to their cloud services and not so many ips available, they change out ips as needed. So, if you are hosting on their server your ip can change as needed. If your Amazon service is not actively using an ip, it can be used by someone else's Amazon service.

This is not uncommon among service providers.

So, to identify what subscriber was using an IP at a certain time the service needs to know:

1. What ip (or ips) are you seeing involved.
2. What time or (times) they were being used. The more detail the better.

So, if you had access to the incoming mail logs for youe email address, that would definitely help. If your email address is hosted on your own domain/server then those logs would be available. If you are using a third party mail service (gmail, aol, yahoo, your isp assigned email address) then you would not have access to them

The header information for the email also helps. You say you used to see the header info in Eudora. Header info is available in most email clients. In some it is harder to get to.

In Live mail, for example, you have to right click a message and go to properties and then the details tab. I think outlook is similar. In gmail (new view, I don't remember the steps in old view) you open the email message and then in the right hand dropdown you choose "show original" and it takes you to a view of the message with the full headers.

Each client or webmail service is different but most allow you to get to the headers some how.

So, what Amazon is asking is not unreasonable at all. imho of course.

What email client are you using?
