Add New Host DNS name
On the domain configuration page, click New Entry to add host DNS name. The following page is shown.
Select type: There are 3 selectable types as below.
1. A (Address):
Set up the mapping of Domain Name and IP Address. For example, address record the mapping
relation of Domain Name and IP Address.
"A" stands for Address, and each record provides each Domain Name map into each IP Address.
Because the host2 server has 2 IP Address, there are 2 records in the data file of DNS. The DNS
request can return not only one IP Address for each Domain Name, and it may sort the DNS
request result via address-sorting or round-robin.
2. CNAME
CNAME stands for the record of alias. The mechanism can provide Record A to have more than
one name (Alias) for querying. For example the 2
formal name, host5.planet.com.tw.
Domain Name
host1.planet.com.tw
host2.planet.com.tw
host2.planet.com.tw
Domain Name
Host5.planet.com.tw
