    What do you use for a local DNS server?

      @johnhooks Thanks for that, however I don't want to have to edit any files.

      How will you run DNS without editing files?

        Pretty much the only DNS server I would run would be BIND if I was putting it on a server.

          I use my Mikrotik router. Had a forum post on config here.

              It's fine, just meant to be a forwarder not a DNS server. It has limited capability to serve out a small text file when needed. If you are going to use it, why not just push hosts files around?

                @scottalanmiller That's a fair point. I guess my problem is my hostnames are changing all the time as I add/remote/change VM's etc.

                  Makes sense. If you are adding or removing with Ansible or Chef that would solve that.

                  Where are you using all of the host names? I do this all the time but I only access them from the jump box normally. Do you have services that need to talk to one another but are being created and destroyed regularly?

                    @scottalanmiller That's the whole reason I want DNS setup. I want to be able to SSH by hostname, not IP address, however I guess your right, maybe I just need to setup the host names on the jumpbox.

                      I saw a presentation at a conference 5 or 6 years ago from an IANA guy. He said they're so paranoid about DNS that they have multiples of everything for the same letter root DNS server. They use hard drives, power supplies, network cables, DNS software, firewalls, etc all from multiple different companies. He also said they've gotten DoS attacks over 10Gbps. He said they were one of the driving forces for NGFW manufacturers to start making firewalls that could do 10Gbps. He said they've been able to sustain DoS attacks and not go down...you guys better! Pretty crazy stuff.

                        that's all that I do. Maintain the /etc/hosts file and I never run into a need to use IP Addresses since I don't SSH from random box to random box.
