                                CGNAT (can be confusing for some Internet   
   features)   
   |        | WAN   
   | Router |----- 21.73.14.115 ------   
   |        |      rogers.ca   
      
   That's intended to conserve addresses, but it may impact things   
   such as geolocation or figuring out whether the Denver Home Depot   
   should appear on my web page as the closed Home Depot to me.   
   Maybe I'm actually in Seattle, and the Home Depot is going to be   
   confused about me manually setting Seattle Home Depot in the web   
   page, when the packets (via their WAN IP) appear related to some   
   Denver ISP.   
      
   That does not come up too often, but occasionally when someone   
   describes a "brokenness", it is traceable to CGNAT usage. Some   
   traffic gets blocked, because "a lot of traffic is coming from   
   21.73.14.115 right now and we think you are attacking us".   
      
   My ISP (a reseller), has three million IPV4 addresses in a WAN pool, and   
   I can be assigned any one of those three million addresses via   
   Dynamic Host Control Protocol (DHCP) or similar, at the ISP building.   
   Maybe I turn off the router, reboot it, and a new WAN IP is   
   assigned to me. By using Firefox to    whatismyip.com , I can see   
   what my new WAN IP is. I don't do this too often, because I don't   
   need to know that value, in order to use the Internet.
