: How to create an own domain name servers i bought an domain from bigrock ,which has dns1.digrock.com and dsn2.bigrock.com as name servers . but some website have there own domain name dns1.domain.com.

@Pierce454

your provider needs to "clone" ( allow zone transfer ) your local dns server, because he has the authoritive servers.

if you want autoritive dns servers you got to provide 2 servers on different ip addresses, the addresses must not be in the same range / subnet

this "quite expensive" to run ( rent 2 root servers )

and for what ? just because it looks "good" ? ;) yes ! .. no! that's not "economic".

if you have other use for your dns servers it becomes more reasonable ....

Rather than create your own, a lot of companies will buy aliases, so they can have their brand on the name servers but would be actually hosted by the same company as before.

This isn't a very expensive service at all. I don't recommend you set up your own name servers for several reasons:


They will be slower (many NS hosts use cloud-infrastructure)
If they go offline, your entire site/operations will go down with it.
There's no point in wasting system resources and man-hours when its not absolutely necessary.
