What is "my IP address"?

[Jonathan Feinberg]

I've had some success with my new GAE application, http://wordle.net/
.

One of its features permits you to visualize your del.icio.us tags.
This feature has been popular enough that del.icio.us has throttled
me. The good news is that my contacts at Yahoo are willing to
whitelist my application. The bad news is that, in order to do so,
they need to know my IP address.

Is there such a thing as a single IP address that my app is "running
on"? Or am I somewhere in an arbitrary cloud of addresses?

Your application is gorgeous!

Thanks. But what IP address is it running on? ;)

why not simply write something to ping a host, perhaps another app engine app, and grab the requesting IP on that host or in that second app?

Nice app Jonathan,

How did you setup a DNS for a naked domain?

I checked you registered your domain through GoDaddy - does thay
support multiple IPs for a single A record?

I've just asked here
http://groups.google.com/group/google-appengine/browse_thread/thread/62c491de1adec073/60fd8d9e01f77bec?lnk=gst&q=naked+domain+ip#60fd8d9e01f77bec

and hope may be you could clarify.

App Engine apps don't exist on any one serve, they are distributed
across google's architecture. Accordingly they don't have a single IP
address. Additionally multiple AppEngine apps will frequently run on
the same server, this means that using an IP address to authenticate
an App Engine app is highly insecure.

In regard to the later DNS question, according to the App Engine docs
(http://code.google.com/appengine/articles/domains.html) the way you
use a custom domain name with App Engine is through google apps for
domains. Basically you link you app engine account to your google
apps for domains account, then you set google's DNS servers as the DNS
servers for your domain. This means you don't need to know the ip
address of your App Engine app and your not limited by the
capabilities of your registrar's DNS servers.

I figured, and agree with all of your comments. Now del.icio.us has to
fix their inherently b0rken whitelisting scheme!

Thanks for the useful information.
