I try searching for this but couldn't find anything. Anyways, what I want to know is if it is possible to have one DNS point to another DNS. Do I just add a DNS zone?
My registrar has ns1.xyz.com and ns2.xyz.com as nameservers for my domain xyz.com. I have a reseller account that lets me edit/add dns zone (through whm) for xyz.com. I have another hosting account using zzz.com but with another hosting company that uses ns1.ppp.com and ns2.ppp.com as nameservers. Is there anyway for me to use ns1.xyz.com and ns2.xyz.com nameservers for my zzz.com domain by somehow adding a DNS zone through my reseller account using whm?
Yes, you can add a DNS zone for zzz.com to your ns1/ns2.xyz.com nameservers through WHM. Just put in the IP address for the website at zzz.com (to find out the IP, just ping zzz.com). Then switch zzz.com's authoritative DNS servers through your domain registrar over from ns1/ns2.ppp.com to ns1/ns2.xyz.com.
