      The new range was researched using Google. It appears to be unused as a company standard default

      Yep.. Nothing is ever wrong on the internet.. ๐Ÿ™„

      That is a scary comment.. You need to use private IP space if you don't want any gottchas down the road.

      10.0.0.0/8
      172.16.0.0/12
      192.168.0.0/16

      172.20.1.1/24 is one I use at a client site..

      VOIP for one is easily broke by using a publicly route-able address as your LAN.

          What is the range you're using? If it's internal it's not like anyone can connect to it, there's no danger in telling us.

            xxx took some research to find one that was not on Google as a default that some company uses or has ever used. I don't want to jinx it as it was a minor pita to change it. I stayed in the 192.168.xxx.0/24 range to make the changeover easy on myself. If I ever have to do it again, I'll figure out something obscure in the 10.0.0.0/8 range.

                    I know what a non-routable IP address is. If you can't tell by what I wrote, you must need a refresher consulting class.

                      I simply find it funny when someone will not show their LAN addresses online.

                      Nope. I cannot see your knowledge or experience from here and can only assume by what you post.

                      Good Luck!

                        Actually, they are routeable. They're just not allowed on the Internet. With your VPN, you are routing those private addresses.

                              Ah I see what you mean now. That's obviously fine. โ˜บ

                              It's very hard to judge peoples level of experience based only on a few forum posts. Which can easily lead to either coming across incredibly patronising or totally incomprehensible. I've done both!
                              I had visions that you might be just using some random public subnet based on a Google search. Glad to see you're not. ๐Ÿ˜‰
