Post by m***@gmail.comPost by David J DachteraPost by m***@gmail.comHi,
Am new to the DNS concepts. As am going through DNS SOA record i
got confused why need to have email feild. I know that we need to
specify the email id of a person who is responsible for that zone (can
i call him as zone owner). I just wants to know why need to specify.
It may have some specific function, weather zone owner will get mails?
if so when he will get mails and who will send those mails?
Can anyone please clarrfy this to me.Thanks in advance.
Protocol. It assumed that the person who is the authority (SOA means Start Of
Authority) for the domain is a responsible individual. Providing a means of
contact provides evidence of this, and should be kept up to date so it matches
the contact information filed with the registrar for that top-level domain.

Hi,
You mean one who is responsible for domain will become the responsible
person for the zones that the domain is hosting and registrar
maintains the contact information of that authority person. If my
understanding is correct then i need one more clarification regarding
this.
I understood that one domain can host multiple zones. In this case
assume that we have registered our domain with registrar, this domain
host three zones, and there are three different persons are
responsible for each zone. Then is registrar maintains all these three
authority persons information? I just want to know in which situation
this email id will be useful? Any practical scenario.
Your company, for example, might be bigco.com. That's your domain and the only
"zone" viewed by the world outside your corporate firewall. Now, you might
"publish" the URL http://custserv.bigco.com/ for your customer service "front
page", but that's just a node within the bigco.com domain/zone.
On the other hand if your company is an ISP, the situation may be more complex;
however, for example, bigisp.com is still the "root" of your ISP's domain
structure. If you sell domain hosting, your customer registers their domain thru
you with the registrar listing, for example, dns1.bigisp.com and dns2.bigisp.com
as the nameservers for their domain; "bigisp" is only the provider - your
CUSTOMER is the authority for their own domain, but you will probably list, for
example, hostmaster.bigisp.com as the technical contact when you file their
domain registration with the registrar (another service you sell).
Does this help?
