i am newbie and i do dont know how to setup my own nameserver with my vps account. i have 1 ip and 256 ram. Say if i have abc.com and i want to setup ns1.abc.com ns2.abc.com - how do i do that? i have no idea.
I guess you need atleast 2 different IPs for a valid set of nameservers. Though 1 IP will do, but some domain registrars don't allow the same IP to be used for 2 nameservers. What control panel do you have? "bind" or "named" is responsible for nameservers and domains.
DirectAdmin is a wise choice! Nameservers for the main domain (admin) is already configured on DA. For other domains, Goto the reseller level > Nameserver Management > Select the IP(s), tick virtual nameservers and submit.
