2 DNS servers

2 routers

1 firewall

1 VPN server

Internal file server

300 user workstations

6 printers

Your ISP has requested that you return the two Class C network addresses that it assigned to your company ten years ago. They will allocate to you six externally routable IP addresses for any external-facing systems.
