Windows – How to create DNS entries on Windows Server, such that a single word (without a TLD) can be used to resolve an ip?
In the Windows Server DNS role, is it possible to create a DNS entry, such that all devices in my network (also those that are not part of the same domain) can resolve a short hostname (eg: 'test') to the host's static ip address without requiring the FQDN (eg: 'test.example.com')?
The best method is via the response policy zone in Bind 9.8.1 or newer. It allows you to override single records in arbitrary zones (and there's no need to create a whole subdomain for that, only the single record you want to change), it allows you to override CNAMEs, etc. Other solutions such as Unbound cannot override CNAMEs.
If you run dig on a different machine just use @the-ip-address-of-Bind-server instead of @127.0.0.1
I've used this technique with great success to override the CNAME for a website I was working on, sending it to a new AWS load balancer that I was just testing. A Raspberry Pi was used to run Bind, and the RPi was also configured to function as a WiFi router - so by connecting devices to the SSID running on the RPi I would get the DNS overrides I needed for testing.
It stands for Fully Qualified Domain Name, i.e. the entire domain name, not a prefix.
Your parsing of your domain name is backwards. com is the top-level domain, mySite is the second-level domain, and www is almost certainly not a domain at all, but a hostname within the domain mySite.com.
What the sentence means is that if the settings that allow a 'partial' domain to be completed (i.e. you enter www, it figures out you mean www.mySite.com) are screwed up, you can work around this by entering the full domain.
