DNS lookup

Use the Tools } DNS Lookup tool to resolve domain names into the corresponding IP address and to retrieve particular information from the target domain (for example, MX record, etc.).

Screenshot 122 - The DNS Lookup tool

To resolve a domain/host name:

1.Click on the Tools } DNS lookup node.

2. Specify the hostname to resolve.

3. Specify the information that you wish to retrieve:

`Basic Information' - Select this option to retrieve the host name and the relative IP address.
`Host Information' - Select this option to retrieve HINFO details. The host information (known as HINFO) generally includes target computer information such as hardware specifications and OS details.

NOTE: Most DNS entries do not contain this information for security reasons.

`Aliases' - Select this option to retrieve information on the `A Records' configured on the target domain.
`MX Records' - Select this option to enumerate all the mail servers and the order (i.e. priority) in which they receive and process emails for the target domain.
`NS Records' - Select this option to specify the "name-servers" that are authoritive for a particular domain or sub domain

4. Specify (if required) the alternative DNS server that will be queried by the DNS Lookup tool or leave as default to use the default DNS server.

5. Click on the Retrieve button to start the process.
