DNS Lookup

You can specify a DNS Hostname for a forward lookup or an IP address for a reverse lookup. You

can also perform a lookup for a Mail (MX) record by prefixing a DNS Hostname with @.

Note: A DNS server must be configured for DNS Lookup to work.

To use forward or reverse DNS lookup, perform the following steps.

1. Click Diagnostics < DNS Lookup. Figure 11-14 shows the page that displays.
