A DNS make you come to the right homepage like subsim.com/radioroom when you enter the name in your URL field. You could also enter subsims ip-adress(numbers) directly.
I could be wrong though.
Edit
Made search on how DNS works and found this
Quote:
DNS allows a domain name to be associated with an IP address. So instead of typing an IP address that consists of a large number of numbers, you can, for example, type Facebook.com in the browser, and then DNS will redirect you to the correct website.
However, it is apparently Facebook's DNS that is down, which is why the website cannot be accessed.
For example, Google has the IP address 172.217.16.67. Here, the DNS Servers ensure that when you enter Google, it is converted to 172.217.16.67.
