NAT use four types of addresses: -> Inside local address - The IP address assigned to a host on the inside network.
The address is usually not an IP address assigned by the Internet Network Information Center (InterNIC) or service provider.
This address is likely to be an RFC 1918 private address.
-> Inside global address - A legitimate IP address assigned by the InterNIC or service provider that represents one or more inside local IP addresses to the outside world.
-> Outside local address - The IP address of an outside host as it is known to the hosts on the inside network.
-> Outside global address - The IP address assigned to a host on the outside network.
The owner of the host assigns this address.
The correct answer is A. outside global.
Network Address Translation (NAT) is a method used by routers to allow multiple devices on a private network to share a single public IP address. NAT works by translating the private IP addresses used by devices on the local network into a public IP address that can be used on the internet.
There are four types of IP addresses involved in NAT:
Inside local address: The IP address assigned to a device on the local network. This is typically a private IP address, such as 192.168.1.10.
Inside global address: The IP address assigned to the NAT device on the public internet. This is the address that the outside world sees when communicating with devices on the local network.
Outside local address: The IP address assigned to a device on the public internet that is communicating with a device on the local network. This is typically a public IP address, but it is not the address that the outside world sees when communicating with devices on the local network.
Outside global address: The IP address assigned to the device on the public internet that is communicating with a device on the local network. This is the address that the outside world sees when communicating with devices on the local network.
In this case, the question is asking for the type of address that the public IP address of the NAT device represents. This is the address that the outside world sees when communicating with devices on the local network, which means it is an outside address. It is also a global address because it is assigned on the public internet.
Therefore, the correct answer is A. outside global.
