Wildcard URL for plugin/core updates?

I just installed a site on a client’s server. The site uses a few plugins, which will need updating.

The server has a firewall that requires whitelisting of URLs. I found this out when I was attempting to register the Revolution Slider plugin. RevSlider’s FAQ’s give you the URL for the whitelist, so I was able to get through and register.

Going forward, I’m guessing we’ll need to add whitelist urls for core and plugin updates. Is there one wildcard url for all the updates that come through www.ads-software.com?

Thanks!
