If your computer is connected to a local network, then you are most likely using a private IP address. There are three designated private address ranges that are reserved for local networks, and they are not accessible from the public internet.
Your router uses a feature called network address translation (NAT) to convert the private addresses of devices on your network to a public address that can be accessed from the internet. This keeps your devices and data safer from outside threats.
Here are the three private address ranges:
1. 10.0.0.0 – 10.255.255.255
Devices on your network assigned an IP address within this range are part of a Class A network. This range is typically used in larger networks or corporations.
2. 172.16.0.0 – 172.31.255.255
This range is also part of a Class A network and is commonly used in smaller networks.
3. 192.168.0.0 – 192.168.255.255
Devices on your network that fall within this range are part of a Class C network. This range is commonly used in home networks or small offices.
By assigning private addresses to devices on your network, you have an additional layer of security between your internal network and the outside world. NAT ensures that these private addresses cannot be accessed from the internet, keeping your devices and data safe.
What is a private IP address?
A private IP address is an IP address that is designated for use on a private network. These IP addresses are not accessible from the public internet.
Why are private IP addresses used?
Private IP addresses are used to provide an additional layer of security between a local network and the internet. They ensure that devices on the network cannot be accessed from outside the network.
What is NAT?
Network address translation (NAT) is a feature used by routers to convert private IP addresses to a public IP address. This allows devices on the local network to access the internet without exposing their private IP addresses.
Can I change my private IP address?
Yes, you can change your private IP address by accessing your router’s settings and assigning a new IP address to a device on your network. However, you should be cautious as this may cause connectivity issues if done incorrectly.
Protect your network with private IP addresses and NAT
By understanding private address ranges and how NAT works to keep your devices safe from outside threats, you can ensure that your network is secure. Keep your private address ranges in mind when setting up a new network or managing an existing one.
