there's something I'm really having a hard time finding somewhere. How is this type of URL made? That is, if I want to make a web application, for example, how do I put the following domain/url? app.myapplication.com

To begin, clarify that, in the example you give in the question,
app
it is simply one more sub-domain ofmiaplicacion.com
, just as it iswww
,ftp
ormail
.Namely,
www.miaplicacion.com
ftp.miaplicacion.com
app.miaplicacion.com
They are the same thing (type A records in the DNS) and are configured in much the same way.
The steps to follow are:
You must have one or more servers, dedicated or shared, where you can manage the configuration of the
DNS
.Buy the domain
miaplicacion.com
and use the address(es) of the serversDNS
we talked about in the previous step as part of the domain registration.Configure the
DNS
initial server with the typical to resolve those related to the domain.Finally, by
DNS
adding a new type recordA
forapp.miaplicacion.com.
and that resolves to the address(es) you have planned to do what you are going to do with the sub-domain, for example, in the case ofes.stackoverflow.com
, what is behind it is web servers (IIS), which at the time of writing this publication are hosted on 4 different IP's:It may be unnecessary, but do not forget that the server or servers that you have destined to provide the service must be configured to provide it. Taking again the case of
es.stackoverflow.com
, it is a web service and the aforementioned port is listening on port 443,IIS
which is capable of recognizing the call to the sub-domain and executing what is necessary to produce the desired result.It is worth saying that many of these steps are solved by buying a typical shared hosting service , just make sure you have control of the DNS of your domain.
