The Dns, Ping and Trace Components

Use the Dns component to access Domain Name Servers. Forward lookup (resolving a host name to an IP address), reverse lookup (resolving an IP address to a host name), and MX lookup (resolve an email address to the mail server responsible for the email address) is fully supported.

Use the Ping component to determine if a host is reachable.

Use the Trace component to identify all of the intermediate hosts which forward a packet to a destination host.
