What is NAT?Network Address Translation (NAT) allows a single device (router) to translate private IP addresses on a private network into public addresses on a public network. NAT service preserves the limited amount of IPv4 addresses. When the internet was first introduced, the only internet protocol available was IPv4. IPv4 has a 4 billion address limitation, so to keep up with the demand, engineers developed NAT. The benefits of NAT also extends to security.How does it affect web log file?NAT affects web logs because every record that is passing through the NAT gateway is being recorded. This is useful because it can help administrators block sites from users and help monitor user traffic in a network.What are some ways that you can view your public IP Address? Discuss the IP Addresses that are not routable.There are countless ways to view your Public IP address. The first is asking Google what your IP address is. The second would be to go to whatismyipaddress.com. The website will pull your IPv4 and IPv6 address. The IP addresses that are not routable are private IP addresses. Some ranges are:10.0.0.0 – 10.255.255.255172.16.0.0 – 172.31.255.255192.168.0.0 – 192.168.255.255These addresses will not be able to route through the internet and require a NAT device to be used.Describe the LAN and WAN addresses on your system, using tools like ipconfig and www.ipchicken.com.LAN IP addresses are your private IP addresses that can stay consistent. They will most likely not change. While WAN IP address will change frequently. If you are curious about finding out what your IP is you can go to www.ipchicken.com and there is a tab that will give you, your current WAN address. While typing Ipconfig /all in your command prompt will give you, your LAN IP address.ReferencesCisco (November 10, 2014). Network Address Translation (NAT) FAQ.

Describe the LAN and WAN addresses on your system, using tools like ipconfig and www.ipchicken.com.Network Address Translation (NAT) is a protocol that was designed to help conserve the limited IP space of IPv4 (Cisco, 2017). In a nutshell, it works by allowing unregistered IP addresses in private networks to connect to the internet through a registered public IP address. This capability gives companies and households the ability to IP up all their devices, but only use one public IP address for their entire network (Cisco, 2017). NAT can actually add a layer of network security because of the way network traffic exits the router. Only the public IP address can be seen outside the private network and only that address is recorded on web log files (CompTIA, 2020). This means that potential threats sniffing network traffic outside of a private network that is using NAT or port address translation (PAT) will only be able to see the public IP addresses, not the private IP addresses (CompTIA, 2020). PAT is a dynamic version of NAT that pairs multiple private IP addresses with on public IP address. Public IP addresses can be viewed through in a multitude of ways. If NAT is not being utilized on your network, a simple Ipconfig /all command in a terminal will display the public IP assigned to the device by its router. If the network is using NAT, this command will only display the private IP address. In this situation, tools such as ipchicken.com will show you the public IP address that the device is using.ReferencesCisco. (2017, May 11). Network Address Translation (NAT) FAQ.
