my.yourdomainname.com,
then you would have to put in my the text box. If you
wish to add A Record for just yourdomainname.com, then you can leave this box blank.
- Destination IPv4 Address: Here you would have to enter the
IPv4 IP Address
of the Web Server, where you wish to host this domain name.
- TTL: This is the Time To Live for this Record,
in seconds. Any Server which once
queries this Record will query it again after this time interval. The ideal TTL is 86400, which is 1 day.

an AAAA Record for
my.yourdomainname.com,
then you would have to put in my the text box. If you

entered as the Zone. If you are configuring the email server for yourdomainname.com, such that you can receive
mails@yourdomainname.com, then you
need to leave this field blank.
- Value: This is the email server domain name. If the email servers
hosting your domain name are managed by you, then you may set the Value in the format -
mail.yourdomainname.com.
If you are using another Internet Service
Provider's email server, then you need to enter a Fully Qualified Domain Name
like mail.isp.com. Note that a Fully Qualified Domain Name always ends
with a "." in the end.

this Record. Any Server which once queries this Record will query it again after
this time interval. The ideal TTL is 86400 which is 1 day. It can not be

to the server with the lowest preference number first, and if
unsuccessful, continue with the next lowest and so on.

then enter the Zone as subdomain.yourdomainname.com in this text box.
- Value: This is the Name of the Name Server to be created or another
Fully Qualified Domain Name that you want to make responsible for this Zone. Thus, if you
wish to create an NS Record for subdomain.yourdomainname.com, you may
enter the value as ns1.subdomain.yourdomainname.com. Or, you may want a Name Server like
ns1.subdomain.yourdomainname.com to be delegated to another Fully Qualified

- Click the Add Record button to submit your Record.
VIII. SOA Parameters
The moment you activate the DNS Service
provided by Whois.com Pte Ltd,
a default Start Of Authority [SOA] Record is created for your domain name. To
modify your SOA Record:
- Click SOA Parameters -> Modify Record.
- There you would find 5 editable fields:
- Responsible Person: The email address of the person responsible
for maintenance of the Zone.
- Refresh:
The Refresh Interval indicates how
often Secondary Name Servers should check if changes are made to the Zone. You
can decide your own value for this Interval.
- Retry:
The Retry Interval indicates how
often the Secondary Name Servers should retry checking, if changes are made - if
the first refresh fails.
- Expire:
The Retry Interval indicates how
long the Zone will be valid after a refresh. Secondary Servers will discard the
Zone, if no refresh could be made within this interval.
- TTL: This is the Time To Live for this Record. Any Server
which once queries this Record will query it again after this time
interval. The ideal TTL is
86400, which is 1 day. It can not be set to less than 14400, i.e. 4 hours.
Apart from these, the SOA Record also includes a parameter Serial.
This is a number that is automatically generated by our Servers. All Secondary
Name Servers cache the Serial Number in the SOA Record, such that when a Serial
Number change is detected by Secondary DNS Servers, it updates its Records with
the changes. This number is automatically increased by our Servers when changes
to the Zone or its Records are made.
- Click the Modify Record button to submit your changes.
IMPORTANT
For the DNS Records you have
thus added to be activated, you are required to make modifications to your domain name's Name
Servers.
