DNS What am i not understanding?


Hello,

I am running DNS on a Linux system more for testing at this stage than anything else. I have a registered domain eziekiel.com so my DNS server is ns.eziekiel.com. I am running BIND 9.2. I have also recently registered with easydns for secondary/redundant dns.

My question is should i have had the need to do that (the need for secondary DNS) to have my domain seen. My registrar is Domain Mongers & in their name server section while i was able to enter easydns name server info for 3 servers i was not able to enter my own even though mine is primary. How is my domain meant to be found if i cannot enter FQDN & IP?

Shouldn't i have been able to enter relevant details on their setup page negating the need for secondary services?

I hope this makes sense

Kind regards

Andrew

Depending on your domain registration company you may need to "register" your name servers so that they can create what is termed a "glue" record.

The "glue" record is used to prevent the situation where something is trying to look up ns.yourdomain.com to find where your name servers are but can't look up anything in yourdomain.com because it doesn't know where the server is.

Further information on glue records here: http://faq.domainmonster.com/dns/glue_record/

Thanks for your reply

So if i understand your reply you if you don't have secondary servers you cannot run a domain via a primary server alone. How can a registrar dictate this choice?

It's nothing to do with the registrar "dictating" anything, it's to do with the fundementals of DNS.

Check with your registrar as to how to register your name servers IP addresses and then you'll be able to use them as the primary ns for your domain.

Note that you really will need a static IP for your NS and not an ISP DHCP address.
