Hi.
Researching dns/naming. (sortof fed!!)
Assume I have a server -rackspace/digitalocean/etc.. And I and I want
to serve the DNS via something like cloudflare.
The test server(s) aren't going to be webservers, they're going to be
used to test apps..
As far as I can tell, most of the sites say you need to already have a
"name" from a domain name provider. That can't be right, can it!! One
can have a dns process internal to an org, providing dns names to
machines all over the place. Granted, those machines/names might be
internal/private.
So, does one need an "actual" real name for an externally facing
server in order to process the DNS so one can do a "ssh t...@foo.com"
or can you use something like "ssh t...@foo.example.com"
yes
At the same time.. if you do need a real/actual "domain name" for the
externally facing box, digitalocean provides for both public/private
networks for the linux instances. If you run a private network, would
you then be able to create your own name for the internal instances
that would be available to the other instances on the private
network??
Pete and Shawn both give good advice. However, if you'd like a quick
solution using a fake domain name *internally* I'd recommend djbdns's
tinydns. tinydns allows you to declare yourself AUTHORITATIVE for zones
without having to connect to the root name servers.
To test this I just created feefle.farfle. and paired it with
53.53.10.in-addr.arpa. and it worked without a hitch. Combined with
dnscache, also part of djbdns, you would have a complete
authority/recursive name server setup for your private space.
If this interests you let me know and I'll contact you off list.
