We live in an era where our digital presence is as tangible as our physical one. Imagine your IP address as the house number of your home in the vast neighborhood of the Internet. Without it, the digital mailman wouldn’t know where to deliver your emails, streaming videos, or the web pages you visit. However, managing this address is not just a technical matter; it deeply affects our privacy and security, especially in the current European regulatory context.
Understanding how to identify and manage your IP address, both public and local, has become an essential skill. You don’t need to be a computer engineer to master these concepts. Whether you are professionals working remotely or students passionate about technology, knowing your network identity allows you to troubleshoot connection issues and protect personal data. In Italy, where digitization is advancing rapidly amidst tradition and innovation, digital awareness is the first step towards safe browsing.
Knowledge of your IP address is the keystone for diagnosing network problems and shielding your online privacy against unwanted intrusions.
Difference Between Public IP and Local IP
To understand how the network works, it is fundamental to distinguish between the two main types of IP addresses. Confusion often arises, but the distinction is clear and functional. Think of your router as the doorman of an apartment building.
The Public IP Address is the one assigned by your Internet Service Provider (ISP). It is the label by which the outside world sees you. It is unique across the global network and identifies your home or business connection. When you browse, websites see this number.
The Local (or Private) IP Address, on the other hand, is used only within your home network (LAN). The router assigns a different number to each connected device: PC, smartphone, printer, or smart TV. This serves to let devices communicate with each other and with the router itself, without exposing them directly to the Internet.
Why it is important to distinguish them
Knowing the difference helps solve specific problems. If no device can browse, the problem is likely with the Public IP or the external line. If only the phone cannot connect, the conflict is with the Local IP. This logic is similar to trying to resolve connectivity issues on messaging platforms; for example, understanding the network helps when WhatsApp Web is not loading content correctly.
How to Find the Public IP Address
Identifying your Public IP is the simplest and most immediate operation. Since this address is visible to any website you visit, you just need to use an online tool. There is no need to access complex operating system settings.
To view it, open your favorite browser and type “my ip” or visit specialized sites. You will see a string of numbers separated by dots (IPv4) or a longer sequence with letters and numbers (IPv6). This data is essential if you need to configure remote access or video surveillance systems accessible from the outside.
It is vital to remember that the Public IP reveals information about your approximate geographic location and your provider. For those concerned about privacy, this is the data that gets masked when using a secure connection or a VPN, a fundamental concept even for those who want to keep WhatsApp Web secure from prying eyes.
Finding Local IP on Windows PC
On Windows, the procedure to find the local address is quick and can be done in two ways: via the graphical interface or the command line. The command line method is often preferred by technicians for its immediacy.
Quick Method: Command Prompt
This is the fastest way to get precise data. Follow these steps:
- Press the Windows + R keys on your keyboard.
- Type cmd and press Enter.
- In the black window that appears, type ipconfig and press Enter.
- Look for the entry IPv4 Address. That is your Local IP (usually starting with 192.168).
Graphical Method: Settings
For those who prefer not to use the terminal, Windows offers a visual path. Go to Settings, select Network & Internet, then click on Wi-Fi (or Ethernet if connected via cable). By clicking on the properties of the current connection, scroll down until you find the technical specifications, where the IPv4 address will be listed.
Finding Local IP on Mac (macOS)
The Apple ecosystem is known for its intuitiveness, and finding the IP address is no exception. Here too, we have both graphical and text-based options, but the graphical route is the most common for the average user.
Open System Settings (or System Preferences in older versions). Click on the Network icon. Select the active connection (Wi-Fi or Ethernet) on the left. Often the IP address is visible directly under the connection status, or by clicking on “Details”.
Expert users on Mac can use the Terminal by typing the command ifconfig for a detailed analysis of all available network interfaces.
Identifying IP on Android and iOS Smartphones
In the mobile era, managing connections from a smartphone is a daily task. Often, synchronization problems between phone and computer arise precisely from IP address conflicts in the local network. This is particularly relevant when encountering the WhatsApp Web phone not connected error, where local network stability is crucial.
Procedure for Android
Since Android has different interfaces depending on the manufacturer (Samsung, Xiaomi, Pixel), menu names may vary slightly. In general:
- Go to Settings and then to Wi-Fi.
- Tap the name of the network you are connected to or the gear/arrow icon next to it.
- Scroll down to the “Network details” or “Advanced” section.
- You will find the IP Address entry clearly indicated.
Procedure for iPhone (iOS)
On iPhone, the operation is standardized and very fast. Open Settings and tap Wi-Fi. You will see the list of networks; tap the blue icon with the “i” (information) next to the connected network. The IP address will be one of the first items displayed.
Security: What Your IP Reveals to Hackers
Many users underestimate the information a simple Public IP address can transmit. Although it does not reveal your full name or exact home address, it provides enough data to create a digital profile or launch targeted attacks.
A malicious actor can deduce your city, approximate zip code, and your Internet provider. This information is often used for Social Engineering attacks or targeted scam attempts. Furthermore, knowing the IP allows scanning the open ports of your router in search of vulnerabilities.
To mitigate these risks, it is advisable to disable UPnP on the router if not necessary and consider using a VPN when browsing on public networks. Network security also influences the performance of messaging applications; a compromised or unstable network is often the cause when WhatsApp Web is slow or does not connect.
The Italian Context: Static vs Dynamic IP
In the Italian telecommunications market, IP address management has some peculiarities. Most consumer offers from operators like TIM, Vodafone, or Fastweb provide for the assignment of a Dynamic Public IP. This means that your address changes every time you restart the modem or after a certain period of time.
Dynamic IP offers a slight advantage in terms of privacy, making long-term tracking more difficult. However, for those who need to access home cameras or home servers from the outside, Dynamic IP is an obstacle. In these cases, one resorts to DDNS (Dynamic DNS) services or requests a Static IP from the provider, often for a fee.
European regulations, including the GDPR, consider the IP address as personal data in many circumstances. This obliges website managers to treat IP address logs with the same care reserved for personal data, ensuring a higher level of protection for European citizens compared to other geographic areas.

Conclusions
Knowing how to find and distinguish your Public IP address from the Local one is a fundamental skill in 2025. It is not just about technique, but digital awareness. Whether you are configuring a network printer, trying to improve your browsing security, or solving connection problems on your smartphone, these numbers are the coordinates of your digital life.
We have seen how simple tools, already integrated into our Windows, macOS, Android, and iOS operating systems, allow us to have complete control over our network identity. In a context like the Italian one, where technological innovation clashes and meets with the daily needs of families and businesses, security starts from the basics. Protecting your IP and understanding how the local network works is the first step for a serene, private, and efficient online experience.
