Before you set up your server, have your DNS server administrator add records for your server to a DNS server. After these records are added, users can access your server by using its host name, such as server.example.com.
Users can use your server’s host name on your intranet if the DNS server administrator for your intranet adds DNS records for your server. If your intranet doesn’t have a DNS server, users can access your server by using its local hostname, such as server.local.
Users can use your server’s host name on the Internet if a DNS hosting service adds the records described below to its DNS servers. These records must point your server’s host name to the public IP address of your Internet router, if you have one. The DNS registrar you obtained a domain name from might provide DNS hosting service, or you can search the web for a provider.
