What is an IP Address?
An IP address, or Internet Protocol address, is a unique numerical label. It is assigned to every device in a computer network that uses the network rule for communication.
An IP address helps devices communicate within a network. It helps to direct data to the correct location. Your device is given an IP whenever you join the internet. This address can stay the same (static) or change over time (dynamic). The address you want to restrict could be linked to:
-
Unwanted traffic
-
Malicious activities
-
Security threats.
Blocking particular IP addresses helps stop unauthorized access. They help to limit harmful addresses from harming your system. You can block a particular IP using your security configurations or gateway. For example, Windows can help you deny access from problematic addresses.
How do IP Addresses Work?
Network Protocol works like a language. It has rules to send and receive data between devices. Devices can talk to each other if they speak the same protocol, no matter where they are. The following is the process of how IP works:
-
Device Connection: Your device connects to a local network with internet access. At home, this network is usually your Internet Service Provider (ISP); at work, it’s the company network. The IP assigned to each linked device helps it communicate.
-
IP Address Assignment: Your ISP gives your device an IP address. This address is used to send and receive data.
-
Routing: Your internet activity goes through the ISP, which uses your IP to send data back to you. The IP can help the ISP find and connect your device.
-
IP Address Changes: If you reset your router or the ISP changes it, your IP can change. You can also block your IP to stop unauthorized access to your network.
-
Traveling with Your Device: If you travel and use a new Wi-Fi network, you will not use your home address. For example, using the network in a hotel or coffee shop. Instead, users will get a temporary IP address from the local network.
Understanding how IP addresses work helps you manage your network better. Users need to block the IP of a device, causing harm or blocking access to a particular IP. They should know how to block them, which can enhance your online security. Restricting IP addresses helps protect your network and improves network management.
2 Types of IP addresses: Old vs New Version
IPv4 and IPv6 are two versions of IP addresses. Both are used to identify devices on the Internet, but they are different in many ways.
1. IPv4 (Internet Protocol version 4)
IPv4 is the older version. It uses a 32-bit address, which means there are about 4.3 billion unique IP addresses. These addresses are written as four numbers separated by periods (e.g., 192.168.1.1). As more devices join the Internet, old IPs are running out.
-
IPv4 is still used the most, but not all devices have enough addresses.
-
It is the primary protocol for devices that connect to the internet.
-
Old IP addresses can be assigned dynamically or statically.
-
Many networks use NAT (Network Address Translation) to handle the shortage of old IPs. This allows multiple devices to share one IP.
-
Old IPs are simple to set up and work with most devices.
2. IPv6 (Internet Protocol version 6)
IPv6 is the newer version designed to solve the problem of limited IP addresses. It uses a 128-bit address format and allows for almost unlimited addresses (about 340 undecillion). Its addresses are written with eight groups of hexadecimal digits (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
-
Next-gen IP provides enough addresses for all devices on the internet.
-
It supports auto-configuration, which makes setting up devices easier.
-
Next-gen IP has built-in security features like IPSec, which protects data on the network.
-
With next-gen IP, NAT is unnecessary because every device gets its unique address.
-
It is designed to work alongside old IP but will replace it in the future.
-
More devices are adopting it, and will help the internet grow.

How does IP Blocking Work?
IP restriction works by blocking traffic from a particular IP address. It prevents unwanted or harmful traffic from reaching your website or network. The following is the process of how it works:
1. Identifying Malicious IPs
The first step is finding the IP address range you intend to block. You can do this by checking network logs or using tools that detect potential threats. Once you find the harmful IP, you can block it.
2. Configuring the Block
You can restrict an IP using a Windows Firewall or a control panel.
-
Open Windows Firewall and click on “new rule”.
-
Set the rule to block the connection from the identified IP address or IP range.
-
You can block multiple addresses if needed by blocking an IP span.
3. Denying Access
After setting the rule, restricted IP addresses cannot connect to your system. This helps to prevent unauthorized access and helps improve your security.
4. Monitoring and Updating
It is important to monitor your data flow to ensure no other IPs are trying to cause harm. You can remove an IP from the deny list through your security settings or control panel if needed.
5. Restrict a Range of IPs
If you see many IP addresses from the same source, you can restrict an IP range instead of just one. It can stop attacks from multiple addresses coming from the exact location. Restricting IP helps protect your system or website from potential threats. You can block the IP to stop access, even if someone uses a proxy. Additionally, in the face of potential threats, blocking access through the use of fast mobile proxy servers can be a proactive security measure.
6. Using Advanced Settings
You can set specific rules to block certain IPs in the custom settings. For example, you can block new addresses or limit inbound traffic from particular areas. It helps create a safer environment for your network or site.
7. Finalizing the Block
Once the rules are set, apply the rule to ensure the restricted addresses can no longer access your website or network.
