Is there a tool/program that would allow me to see all the DNS queries being made on a PC real time?  I would like to be able to load a web page or run a program and see all the FQDN's referenced and looked up via DNS.

We use a L7 firewall and find it troublesome to give someone access to a single web site since no web site loads from a single IP address anymore.  When using browser DEV tools/view, you can see IP ADDRESS, but this is usually ineffective when a CDN is used and moves dynamically to various IPs/server farms.  I would like to see the FQDN names used by web sites and servers by tracking all the DNS queries made on my machine realtime so I can then use those to build firewall rules.

I'm amazed at how many SaaS services still list IP ranges for firewall access and none can give you FQDNs!?!?!
