hosting nameserver problem

I brought a reseller and i sell only share hosting i am not here for advertise and seller allowed me private nameserver, i give my one client private nameserver but my client nameservers are not update world wide

http://www.intodns.com/hrexcellence.biz

please tell me what did i do wrong or my client

 

I don't see any error after accessing the intodns.

 

yes now it's works and 2nd question is my if i any new client so i have add new DNS zone every time

 

It depends on the control panel you use in the server. If you are using, and the add a domain everything will be setup automatically. You will need to update nameservers at registrar end only.

 

how do i know which control panel i am using i mean i using whm

 

changing nameserver record on domain name may take up to 48 hours to propagate worldwide

 

^This. It takes a bit of time for everything to update throughout the internet. They also may need to clear their browser cache and/or their local dns resolver cache.
