The
dnsPromises.resolve6() method is an inbuilt application programming interface of the promises of dns module which is used to resolve IPv6 address ('AAAA' record) for the specified hostname using DNS protocol.
Syntax:
dnsPromises.resolve6( hostname, options )
Parameters: This method has two parameters as mentioned above and described below:
- hostname: This parameter specifies a string which denotes the hostname to be resolved.
- options: It is in the form of an object.
- ttl: It is a Boolean parameter, specifies whether the Time-To-Live value (TTL) for each record to be retrieved or not. If set to true, TTL for each record is retrieved (in seconds).
Return Value: This method returns error, records.
Below examples illustrate the use of
dnsPromises.resolve6() method in Node.js:
Example 1:
Output:
from async:
[ 'fd00:0:13:13::22da:3e74' ]
[ 'fd00:0:13:13::22da:3e74' ]
Example 2:
Output:
from async:
[ { address: 'fd00:0:13:13::22da:3e74', ttl: 30 } ]
Note: The above program will compile and run by using the
node index.js command.
