An IPv4 address is a number that uniquely identifies a device on the Internet. The format of an IPv4 address is four decimal numbers separated by periods, such as 192.168.1.1.

Each decimal number can range from 0 to 255.IPv4 addresses are assigned to computers by routers or DHCP servers.People often ask: how to find my IPv4.

Different types of IPv4

When you use a terminal, whether on Windows or Linux, you will find that there are different types of IPv4 addresses.

There are three types of IPv4 addresses:

Unicast addresses are assigned to individual devices. Your phone and laptop have different unicast addresses.
Broadcast addresses are used to send messages to all devices on a network. Your phone and laptop share the same broadcast address.
Multicast addresses are used to send messages to a group of devices.

What is the purpose of IPv4?

IPv4 is used to route packets of data between devices on the Internet. When a device wants to send data to another device, it first needs to know the IPv4 address of the destination device.

The source device then encapsulates the packet with the destination device’s IPv4 address and sends it to its default gateway. The default gateway is a router that knows how to route packets to other networks.

The router then forwards the packet to the next router, and so on, until the packet reaches the destination device.

IPv4 is a simple and efficient protocol that has been used for many years. It is also widely supported by network devices and software.

Because you need an IPv4 to connect to the Internet, other people can see your device’s IPv4. These are a few ways that other people can see your IPv4 address:

When you visit a website: When you visit a website, your computer’s IPv4 address is sent to the website’s server. This allows the website to know where to send the data that you request.

When you connect to a service: When you connect to a service, such as an online game or a file-sharing service, your IPv4 address is also sent to the service’s server. This allows the service to know where to send your data and to identify you.

When you use a public Wi-Fi network: When you connect to a public Wi-Fi network, your IPv4 address is visible to the network administrator. This is because the network administrator needs to know your address in order to route your traffic.

Generally, there is no harm in having your IPv4 seen by other people. But if you are concerned, there are a few things that you can do to protect your privacy. You can use a VPN, a proxy server, or an open-source software like Tor.
