I am trying to understand the DNS. Say I have a domain named
mydomain.com. And let's say that we have the following FQDNs:
Now my question is, what can I infer given this information?
For example, can I infer that
sub01.sub0.mydomain.com are geographically located in similar locations? (Because they are under the same subdomain:
sub0.mydomain.com). Or is it completely possible that one of them is located in say, US and the other in China?
If not, what can I infer given this list of FQDNs? In other words, what is the purpose of the subdomain system?
sub00.sub0.mydomain.com points to a computer, is it possible that
sub0.mydomain.com points to a computer as well?
