an IP address (Internet protocol address) A unique numeric identifier assigned to all devices connected to the Internet or local network. This address allows devices to locate and communicate with each other. Think of it as the “digital home address” of a computer, smartphone, or other internet-connected device.
Why do I need an IP address?
1. Device Identification
The IP address ensures that the Internet knows where the data is sent. When you visit the website, the device sends a request to the server, and the IP address helps the server provide the correct response.
2. Device Communication
Allow devices such as computers, smartphones, printers, and servers to interact within the network.
IP address type
There are two main versions of IP addresses:
IPv4 (Internet Protocol Version 4)
- format: Four numbers separated by dots (e.g. 192.168.1.1).
- Each number ranges from 0 to 255 and provides the surroundings 4 billion possible addresses.
- Today, the most widely used IPv4 addresses are becoming rare due to the increasing number of internet-connected devices.
IPv6 (Internet Protocol Version 6)
- format: Eight groups of four hexadecimal numbers separated by colons (e.g. 2001:0DB8:85A3:0000:0000:8A2E:0370:7334).
- Designed to overcome IPv4 limitations, offering ~340 ondecillion unique address.
- Ensures future scalability of new technologies.
IP addresses can also be classified according to their assignment method.
- Static IP Address – Permanently allocated to devices commonly used for servers and critical services.
- Dynamic IP Address – It may be assigned temporarily (usually by a DHCP server) and may be changed upon reconnection. They are often used in home networks.
Why do you need to know your IP address?
Understanding IP addresses is important in a variety of scenarios.
1. Troubleshooting network issues
- Diagnosing connectivity issues (for example, if the website is not loading).
- running ping test or Traceroute Identify network failures.
2. Network Device Configuration
- Your Access Router Management Panel (The router IP is required).
- set up Port forwarding For gaming, remote access, or hosting services.
3. Protecting privacy and security
- Detects unauthorized access to the network.
- use VPN or proxy service Mask the real IP for anonymity.
4. Remote Access and Online Activities
- connection Work server, home security system, or smart device.
- Joining Limited Webinar or Streaming Services IP verification is required.
How to find an IP address
On Windows
- Command Prompt: Press Win + R, type CMD, then enter IPConfig. Look for an IPv4 address under an active connection.
Network Settings:
- I’m going Settings > Network and Internet > Status >
- View hardware and connection properties.
Task Manager:
- open Task Manager > Performance Tab > Wi-Fi/Ethernet section.
On Android
- open Settings> wi-fitap on the connected network to find it IP address It is listed.
iOS (iPhone/iPad)
- I’m going Settings> wi-fitap “I” icon Next to the network, check IPv4 address Field.
Find an external (public) IP
- Please visit the IP Check Service. This indicates the addresses that appear on the Internet.
Can I find someone else’s IP address?
Yes, but there are restrictions:
- External IP: It may appear in Email Header Or server logs if you are interacting online (unless you use a VPN/proxy).
- Internal IP: Can only be detected within Same local network (eg, via ipconfig or router configuration).
Note: Tracking someone else’s IPS without your consent could violate privacy laws.

How to hide an IP address
1. Proxy service (Berluk))
- Masking IP by routing traffic through intermediate servers.
- advantage:
- Anonymous – Hides the actual IP.
- Geospoofing – Access locally locked content.
- Multiprotocol support – Works with browsers and apps.
2. VPN (Virtual Private Network)
- Encrypt and assign connections New IP address.
- For better security, choose a reputable provider.
3. TOR Browser
- Routing traffic through multiple nodes Maximum anonymity (Slow but very safe).
