UPDATE:

Target website resolves at Starbucks. Is it a combination of configuration adjustments on the router and the Macbook that are required to enable DNS?

    I can get to this site on Safari, Firefox and Google Chrome, latest versions, on macOS 10.13.6; and also on the latest versions of the same apps in my iPhone running iOS 12. I see that your using Google's DNS servers (8.8.8.8.) Have you tried other DNS servers? Also - what version of macOS and Safari are you using? – IconDaemon Oct 3 '18 at 16:23
  • The error message from Safari doesn't mean it didn't resolve. It means that it couldn't connect. The question is, can you ping that server? Also, if you issue the command curl http://www.fbo.gov you get a 301 error message redirecting you to the same URL but with an https protocol. – Allan Oct 3 '18 at 18:50
  • Good questions. I have updated the OP to address configuration questions and added test results from the Starbucks Wifi connection. I did not try other DNS servers because the Google DNS servers able to resolve the FQDN on the PC (Windows 7). – gatorback Oct 3 '18 at 18:52
  • @Allan: The dig URL command did not return an IP address in the home router test, but did return a IP address at Starbucks: doesn't his confirm it is a DNS resolution issue? I have update the post with the dig results – gatorback Oct 3 '18 at 18:59
  • What do you get with a ping? Also, why are you forcing the DNS server 8.8.8.8. And given that it seems manually set somewhere (rather than use the DNS provided by your ISP), it makes no sense that a dig request would return two different values from the same DNS server when connected to two different networks. – Allan Oct 3 '18 at 19:03
