Description:
If you apply for multiple IP addresses from your ISP, you can assign these public IP
addresses to the IAD and public server, e.g., Web or FTP server. Typically the first
IP is network address, the second is used as the IAD IP address and the last one is
for subnet broadcasting. Other remaining IP addresses can be assigned to PCs on
the LAN.
