Public DNS resolver availability

[clehner]

The DNS page lists a public IP address for a DNS server: https://github.com/nycmeshnet/docs/blob/6ed7b1cea987f333d2c919e611c4255408bac978/content/networking/dns.md#top-level-domains

199.167.59.10 - Public DNS Resolver for anyone in the world. No Logs, No filtering.

I see the host 199.167.59.10 answers DNS queries from inside the mesh, including for the .mesh TLD. However, I don't find it to be reachable from outside the mesh - via DNS queries or pings.
Here is traceroute info from a DigitalOcean NYC3 VPS:

Possible fixes for this issue:

1. Update the page to clarify that 199.167.59.10 is only for use in the mesh (and/or other specific networks?)
2. Enable 199.167.59.10 to respond to DNS queries from outside the mesh.

Greetings,
Talked about also in #157 , I'm putting here an example of resolving that works. Please let me know if otherwise

$ nslookup mail.mesh.nycmesh.net 199.167.59.10
Server:		199.167.59.10
Address:	199.167.59.10#53

Non-authoritative answer:
Name:	mail.mesh.nycmesh.net
Address: 10.70.140.70

$ nslookup google.com 199.167.59.10
Server:		199.167.59.10
Address:	199.167.59.10#53

Non-authoritative answer:

nslookup mail.mesh.nycmesh.net 199.167.59.10 [...]

I see these resolutions working only from within the mesh. I am still finding that 199.167.59.10 is unreachable outside the mesh. From two networks, pinging it results in Destination Net Unreachable from 206.82.104.151. From other networks I get no response. However, I find that changing 10 to 11 works. 199.167.59.11 appears to be a functioning public resolver for mesh.nycmesh.net (including for .mesh TLD). Perhaps the docs should be updated to use that address instead?
