What is a subdomain entry ?
First of all, a subdomain is an additional hostname of a domain.
For example, the user dashboard is using a the "app" subdomain : app.axenthost.com.
Cloudflare is a company providing multiple services for the web. AxentHost use ont of them to handle its
DNS (Domain Name System) entries.
There are many DNS entry types availables, but AxentHost uses only two of them :
A (Address) : This record type allows to associate an IP address to a domain/subdomain.
SRV (Service Resource Records) : Used for minecraft servers. This record is useful to show no port to the user and get a better URL.
What is a DNS propagation ?
Changing a subdomain is great, but it does not apply instantly all around the world. A DNS entry such as
a subdomain needs to be update all accross the Internet. Using AxentHost, a server subdomain takes
arount 2 minutes to be effective.
Once those minutes gone, you can start playing back on your server sharing the new URL to your friends.
