IP addresses of some services?

[AnatoliiTerentiev]

Dear Gurus!

To configure the firewall I should specify the addresses on the Internet, which I needed for my silverlight project.

When I use next code:

<esri:Map x:Name="myMap" Background="White" WrapAround="true"

          Extent="3200000,8500000,4250000,10130000">

            <esri:OpenStreetMapLayer ID="OSMLayer" Style="Mapnik" />

</esri:Map>

the program hangs .I suppose that the service is unreachable perhaps due to the firewall in the enterprise. How do I find out the addresses, requied for services?

I would recommend you to use fiddler to look at requests sent to the servers.

For OpenStreetMapLayer, the servers are depending on the style.

For Mapnik style, the servers are  http://<domain>.tile.openstreetmap.org with domain equals a, b or c.

You can get the current IP addresses of these servers but I would not rely on them for configuring your firewall since nothing prevent these IP from being changed.

Thank you, Dominique!

I thought about fiddler or fireshark.

P.S. All works.
