How Do People Do This

Well I Am A Bit Confused And Curious To Know How This Is Done

Ok What i wanna know is

when i did whois on some sites i found that thier namerservers were

Name Servers:
      ns1.domainsite.com
      ns2.domainsite.com
      ns3.domainsite.com
      ns4.domainsite.com 

Code (markup):

Now How Do People Do This are these people using domainsite hosting coz

domainsite hosting gives only

100 MB Disk Space
5 GB Data Transfer

Code (markup):

and i am sure these sites use more than that much of bandwith and space

So if you guys know do lemme know

thanks

 

They pay additional money for space / BW ?

 

Domainsite also offers DNS management, email forwarders and domain forwards. If you set your domain nameservers to
ns1.domainsite.com
ns2.domainsite.com
ns3.domainsite.com
ns4.domainsite.com

and your domain is registred with domainsite, you can setup email forwarding, domain forwarding or dns management at domainsite

That's why

If you need any more clarification, just let me know ..
