Is there any way to change the IP address of a GAE application when getting url from other site?

[Mike Ye]

Hi,
I am developing a GAE application, want to get other data from some
website W. And this W site has some restrict for request per IP.
I thought that my GAE app will get dynamic IP address every time when
sending request to W site.
But after testing, I find that every time , my GAE app always use the
same IP address.

So, is there any way to control or change the IP address when sending
request to other web site?

Thanks

No. It might be the same IP for a while, but its not garenteed. And
instance starting up on a new server might well suddenly making
requests from a new IP. Scheduled maintaince is almost certainly
garenteed to cause a new IP address.

See if that site allows some other form of security?

- because other apps on AppEngine are using the same set of IPs it
doesnt restrict access to your app anyway.

If you need more control will need to make requests via a proxy.

Hi Qiwei,
No, you can not control that, URLFetches come from a pool of IP addresses.

Perhaps you can work with the service provider, or use some other
machines as proxies for your request?
