How To Modify
Through the myhosting.com Control Panel
you can make changes to your DNS record, including NS, MX, A and CNAME
record modifications. This feature is supported with all hosting plans
with the exception of Domain Parking and Domain/Email Forwarding.
Reasons for Modifying a DNS Record
The reasons for modifying your DNS record may vary. For example, you
may host your site at myhosting.com but want to host your email
elsewhere. This is a scenario in which you may need to modify your MX
Record or Mail Exchange Record. Other examples may include adding an A
Record or CNAME Record which point to another server, or even delegating
a sub-domain to a different hosting server via a NS Record.
In general we recommend that DNS Management be used by
Intermediate or Advanced users. If you are not sure what you are doing,
we recommend contacting our Customer Support department for assistance.
Reset DNS Record
We highly recommend that you not make any changes to your DNS record
unless you know exactly what changes are required. However, it's
possible that some changes in your DNS record may cause your hosting
account or email service to stop functioning properly. If this happens,
you can use the "Reset DNS Record" button at the bottom of the DNS
Management page to reset your DNS record to the default for your hosting
Normally any changes in your DNS record will take 5 minutes to be
updated on the server, and at least 1 hour before the TTL expires and
external name servers pick up your changes.
In some cases, there are DNS entries which are protected and that we
do not allow users to edit or delete. In these cases, either the "Edit"
and "Delete" icons will be missing, or you'll notice a "Cannot edit a
protected record" error.
For myhosting.com customers, this refers to the NS Records that
are used to direct queries to your domain name to our name servers. The
result of changing these records would be similar to the Domain / Email
Forwarding plan. If you wish to use such a redirection, we suggest that
you downgrade your account instead.
For customers of mail2web.com Business Exchange, this refers to
any MX Records or A Records corresponding to the Business Exchange
service. Changing any of these entries may result in your Business
Exchange service to stop functioning correctly, and therefore these
changes are not allowed.
Delay Between Change and Update
Any changes to you make to your DNS Record will be updated on our DNS
Servers within approximately 5 minutes. The default Minimum TTL for all
accounts is 3600 seconds, or 60 minutes. Therefore you can expect your
change to be reflected on external DNS servers within 65 minutes of
making the changes.
Please Note: We cannot control when external DNS servers
refresh their cache and cannot force an external DNS server to update if
it has not done so within the 65 minute time frame.
The @ Symbol in the DNS Record
The @ symbol in your DNS record refers to the record for your domain name without any www or sub-domain name.
For example, the A Record which appears like:
The result of this record is that visitors can connect to your domain name at http://your-domain.com.
You may also notice the @ symbol in the CNAME section:
This will create aliases to the @ A Record, which will point www.your-domain.com and ftp.your-domain.com to the same IP address.
The @ symbol may also be used in an MX record. For example:
@ mail 1
This indicates that the primary MX record for the email sent to @your-domain.com points to the A-record called "mail".
