How to find the URL of a site in IIS?

Question

How do I found the external URL for a site in IIS 8.5 that doesn't list a host name in the bindings?

I've got a client who has given me access to their web server and asked me to find the URL for their live and test sites. The live site is called Default Web Site in IIS. It has two site bindings: one for port 80, one for 443; neither have a host name. The one for 443 has a security certificate that mentions the URL www.companyname.com. If I go to that URL from my computer, I can get to it fine. The problem is the test site. It's set up in IIS as a site called Test with two bindings: one for port 8080, one for port 8081. The binding for port 8081 has the same security certificate as the live site. Of course, that URL takes me to the live site. How do I find the URL for the test site?

Here's what I'm seeing in IIS for the test site:

Solution

Figured it out through trial and error. The main site uses the URL in the security certificate: www.companyname.com. The test site uses the same URL with the port specified in IIS: www.companyname.com:8081.
