I hadn't noticed, but did login to store.service-now.com and do not see an app.  I'm not sure why, but they totally abandoned it.  I even asked for the code if they weren't going to support it going forward.  Nothing.  I do understand it is a commitment as we upgrade ServiceNow twice a year.  Ours stopped working after one of the upgrades and hasn't worked since. 

I have accomplished this by using (and modifying) the Additional General Information extension. It is fairly easy to add additional fields to the extension and pull the information using WMI. I have added DHCP Server Address, DHCP Enabled, IP address (WMI pulls both IPv4 and IPv6), DHCP Server Address, and Domain Name.
