Question

NAT is a very commonly used technique to provide internet access for a LAN. NAT uses a single public IP address to provide connectivity for many private, internal IP addresses. In fact, you are probably using a private IP address on the device you are reading this from.

If I told you that my IP address was 172.19.250.17, what information does that give you?

Answer 1

If you told me that your IP address was 172.19.250.17, it would provide information about the type of network you are on and the use of private IP addresses.

Network Address Translation (NAT) is commonly used to handle the translation between private and public IP addresses.

Step-by-step explanation:

Private IP addresses are used within local area networks (LANs) and are not directly accessible from the internet. They are typically used for devices within a home or office network.

In this case, if you told me that your IP address was 172.19.250.17, it would give me some information about the type of network you are on. The IP address you provided falls into the range of private IP addresses.

Private IP addresses allow for more efficient use of IP addresses as only one public IP address is needed for multiple devices to access the internet. Network Address Translation (NAT) is commonly used to handle the translation between private IP addresses and the public IP address. NAT allows multiple devices within a LAN to share the same public IP address when accessing the internet.

In order to access the internet, devices with private IP addresses rely on a router or gateway device that performs the NAT function. The router or gateway assigns private IP addresses to devices within the LAN, and when those devices communicate with the internet, the router translates the private IP addresses to the public IP address.
