Re: Changing IPs

[Michael Hermus]

You said 'the first connection will be dropped'; it sounds like you expect to have a persistent, long lived connection to the client. This could be a problem unless the client is using a backend to perform all the API calls to your servers.

I don't think that backends are guaranteed a permanent, stable IP address, but it may remain the same for the duration of its up-time, which might be good enough for your purposes. It is also not a unique IP, so depending on how large your client base is, you may have to factor that in as well.

Hello.  This is my first post here.  My company has a prospective client who wants to use our API to write an application that will query servers that we host, and they want to host their app using GAE.  Our servers collect the client IP, and if the same user attempts to connect from a different IP the first connection will be dropped.  Based on the reading I've done in this forum, it sounds like that might be a problem.  Is it accurate that one request from an application might be sent up from one IP, and a subsequent request might use a different IP?

 

Thanks in advance!

Hi Michael.  Thanks for the reply.  Yes, we do expect a persistent connection, and a stable IP per session.  DHCP is fine, as long as there is only IP associated with one username per session.  If our backend sees a request from <username> on xxx.xxx.xxx.xxx, and then another from same <username> on yyy.yyy.yyy.yyy then there would be problems.  I guess the thing to do is set up an account and test our samples.

Set up a proxy. Also anyone using IP address for security is doing it wrong.
