The purpose of an address record is to map a hostname to an IP address. This allows our name servers to give a definitive answer when they receive a DNS query for the corresponding domain. Please make sure that you have created a zone before proceeding with the instructions in this tutorial.
Follow these steps to add an address record:
Modify a zone.
Add a record.
Select a type of address record.
Define the record's hostname.
Assign a DNS TTL.
Define IP address(es).
Save the zone.
Step 1: Modify a Zone
It is mandatory to associate an address record with a zone.
The Routing page allows you to see a zone's configuration.
Step 2: Add a Record
Create a record for a zone.
Click Add Record.
Step 3: Select a Type of Address Record
It is important to note that two types of address records can be created, which are A records and AAAA records. A record points to a hostname on an IPv4 address, while a AAAA record points to an IPv6 address. In this tutorial, we will create an A record.
Make sure that the Type is set to "A (IPv4 Address)."
Name and TTL options will be assigned default values. The Value option will display a hint as to what the correct format should be in order to specify the IP address that is being specified.
Step 4: Define the Record's Hostname
Normally, the name associated with an address record is usually referred to as a hostname. A hostname that is associated with an address record is tied to a zone name. For example, a "www" address record associated with a zone called "mydomain.com" identifies a domain called "www.mydomain.com".
Set the Name option to "www."
Step 5: Assign a DNS TTL
There is a TTL associated with each address record that determines how long, in seconds, a recursive name server can cache a response to DNS queries made to a particular hostname. Suppose your address record has a TTL of 3600 seconds. If this is the case, it may take an hour for all recursive name servers to reflect any changes you make to your address record.
Set the address record's TTL to 3600 seconds.
Step 6: Define IP Address(es)
Finally, we need to define the IP address that will be associated with the address record. This is the IP address that our name servers will provide in response to DNS queries made to the corresponding hostname.
Set the A record's Value option to an IPv4 address.
Step 7: Save the Record
The address record will not be created until the zone is saved.
