Name server or Domain Name System is the system that is used to translate human-memorable domain names like blogger.com and hostnames like belajarbloggingdengan.blogspot.com into corresponding numeric Internet Protocol or IP addresses as well as to identify and locate computer systems and resources on the internet.
Domain name servers are a fundamental part of Domain Name System. Nameserver is a server on the internet specialized in handling queries regarding the location of the domain name's various services. In short, name servers define your domain's current DNS provider.
Usually all domains have at least two DNS servers. All domain registered with Exabytes Network Indonesia and their values are: ns1.idcloudhosting.com
ns2.idcloudhosting.com
When you make a request for anything to the domain name, it gets sent to one of the nameservers. In response, the DNS server sends back the IP address. The DNS then responded back with appropriate IP addresses. This works for website, mail servers and anything else based on the domain name.
After you enter the new nameservers you must save the changes.
Now you have to wait for DNS Propagation or the process of DNS changes to be updated accross internet. This process can be monitored with www.whatsmydns.net.
Yes. If you point your domain at exabytes to a new host by changing the nameservers, you will need to make sure the correct MX Records for your email service are stored in the zone file with the new host. However if you keep the domain pointed at GoDaddy nameservers, your zone file records should stay the same.
