Using the ICMP protocol, Wan Monitor scans specified devices for an UP or DOWN status. A text log is maintained of the UP or DOWN status of sites. To supplement the log entry, an email notification can also be sent to a set of predefined email addresses. As a bonus, Wan Monitor lets you perform DNS queries of Internet sites.
