DNS setup question Centos 7

OK, I did the steps over and still I can’t get anything to resolve. I’m thinking I have an IP address or two in the wrong place and am just not seeing it right now.

I’m pretty sure all the pieces are in place but I’m tired of looking at it so was hoping someone could take a look and point me in the right direction. I’ll post whatever config files would help or all of them if that would be helpful, at least the relevant parts. I’ll start with the one on ns1.

Here are my Droplets

• Marmot
  • IPv4: 104.131.131.228
  • Prvt: 10.134.12.131
• ns1
  • IPv4: 45.55.8.33
  • Prvt: 10.134.27.140
• ns2
  • IPv4: 45.55.8.46
  • Prvt: 10.134.28.123

Here’s my named.conf

acl "trusted" {
        10.134.27.140;    # ns1 - can be set to localhost
        10.134.28.123;    # ns2
        45.55.8.33;  # host1
        45.55.8.46;  # host2
};
options {
        listen-on port 53 { 127.0.0.1; 10.134.27.140; };
#      listen-on-v6 port 53 { ::1; };
        directory       "/var/named";
        dump-file       "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        memstatistics-file "/var/named/data/named_mem_stats.txt";
        allow-query     { trusted; };
        allow-transfer { 10.134.28.123; };

Here’s my named.conf.local

zone "neilanuskiewicz.com" {
    type master;
    file "/etc/named/zones/db.neilanuskiewicz.com"; # zone file path
    };
zone "134.10.in-addr.arpa" {
    type master;
    file "/etc/named/zones/db.10.134";  # 10.134.0.0/16 subnet
    };

Actually, I’m beginning to think that ONLY private DNS is possible with the DO Centos 7 setup. Am I right on that? Maybe I need to switch to a diff distro?

I was going to switch the IP’s around as obviously you need your name servers to be resolveable from the outside world when I read more carefully and it appears the instructions are saying this is only internal DNS for using in your own VPN? This is sort of a bummer as I really wanted to go through the entire process of setting up and running DNS.

update: I’m going to attempt this using only the public IP addresses and see if that works

Wow, DNS can be frustrating. I realize there are tools and services that make it easier but I wanted to understand how it works. I’m not sure if people really directly setup DNS any more but if it’s needed, I"d be happy to write it up for the KB. I’m doing this more to learn DNS than because it’s really necessary to set it up manually. I’m not getting any specific error messages, I’ve not not been able to get the domain to resolve.
