The command that can provide information about the IP address of a Linux laptop connected to a wireless network is "ifconfig". By running this command, you will be able to see the IP address assigned to the wireless interface, such as "wlan0" or "wlan1".
1. You have decided to use SNAT and PAT on your small office network. At minimum, how many IP addresses must you obtain from your ISP for all five clients in your office to be able to access servers on the Internet?
To ensure that all five clients in your office can access servers on the Internet using SNAT (Source Network Address Translation) and PAT (Port Address Translation), you will need at least one public IP address from your ISP.
With a single public IP address, your router/firewall can perform NAT and PAT to allow multiple clients to share the same IP address but use different ports. This way, all clients will be able to access servers on the Internet.
So, in this case, you need to obtain only one public IP address from your ISP.
