Domain Name Server (DNS) used for name resolving to any hosts.
Master DNS servers (Primary Server) are the original zone data handlers and Slave DNS server (Secondary Server) are just a backup servers which is used to copy the same zone information’s from the master servers.
The login information was initialized to be the same as your FTP login when the Windows hosting plan was first created.
This worked beautifully on my Cent OS 6.4 system and gave me node and npm.
I got node 0.10.13, just a little off the latest src tarball 0.10.15.
If they don’t have info about such requested query they will pass the request to the Top Level domain (TLD), if TLD say I don’t know the request, may be the authoritative server know your request, it will forward to authoritative servers, here only defined as address .56.
In mean time authoritative server will give the answer to TLD and TLD will pass to root server and root will provide the info to browser, hence the browser will cache the DNS request for future use.
