I am using dedicated server from iweb.com for my site. manager of my server sets dns Name Server: NS1.DNSEXIT.COM (has 21,361 domains) Name Server: NS2.DNSEXIT.COM (has 21,361 domains) my site is www.iransalamat.com question is it is better to have dns like this(as example) ns1.iransalamat.com ns2.iransalamat.com or NS1.DNSEXIT.COM NS2.DNSEXIT.COM is correct? I mean that setting making cause problem? sorry for my poor english
Do you mean "What is better - to host my DNS zone on my dedicated server or on the big special DNS server?"? I think that uptime of DNS server with 21k domains will be better...
I think what he means is, he wants to have his own private nameservers. ns1.iransalamat.com ns2.iransalamat.com
I mean which type of dns setting is better for working my site perfectly ns1.iransalamat.com ns2.iransalamat.com or that type of current setting Name Server: NS1.DNSEXIT.COM (has 21,361 domains) Name Server: NS2.DNSEXIT.COM (has 21,361 domains) my domain is www.iransalamat.com
I can guess that ns#.iransalamat.com is mapped to the IPs on your dedicated server and NS#.DNSEXIT.COM are specialized DNS servers of some provider. But information you gave is just some names... If you are about performance of DNS server depending of number of domains hosted - don't think there is some difference because of DNS server nature and caching. Uptime is the main. And why not to assign 4 nameservers and not worrying?
yes it is better to assign for nameservers... it is not so expensive just getting information about current setting Name Server: NS1.DNSEXIT.COM (has 21,361 domains) Name Server: NS2.DNSEXIT.COM (has 21,361 domains)
