PS:
And what happens if there are multiple domains hosted on a single server'? All this is independent of how many ways there are too find this server. At a basic level, you can point as many DNS names as you want at a servers IP(s) and it won't even know how you got it. Some protocols (TLS, HTTP) allow specifying the name you were looking for in the communication ( so you can hoist multiple websites on one IP) but these are independent of the server's hostname and even the DNS names that point at it (except by convention). /MR
