I am reseller, I have reselling accounts with two different companies i.e. two different servers.
The first one on domain xxx.com has my own private name servers ns1.xxx.com and ns2.xxx.com. I have registerd these servers with the registrar and have hosting for domain xxx.com at company1 and compay1 set my nameservers on their server. This is all working fine for the past two years.
Now I have openeda new reseller account with company2. Now I want to use private name servers ns3.xxx.com and ns4.xxx.com for my hosting accounts at company2. Is this possible, if so any body can explain how to do this.
