There are many ways to identify a person uniquely Eg:Passport,Aadhar no etc.
Similarly IP adress is used to identify a host/router uniquely.
Lets say I have my enterprise application server at an IP address. But the world knows it as "sup123.com".
How do I map this name with my IP address?
Thats the job of DNS.It is an application layer protocol to provide mapping between domain names and IP addresses.
Go to manage dns records section of you domain registrar's site.
Delete all default records.
Set up 4 records as shown above
Type A resolves to IPV4 address Type AAAA resolves to your IPV6 address
www, @ make it both available at w ww.xyz.com as well as xyz.com
You can refer your IP adresses from your vps/shared server's access details.
And your mapping will be done!!
