Monitoring Internet Usage: Tracking Activity By Ip Addresses

Monitoring internet usage by IP address is a useful way to keep an eye on bandwidth-hungry devices, check for unauthorised connections, and troubleshoot problems. To do this, you can use your router, which processes all incoming and outgoing internet traffic for your home. By logging into your router's web-based interface, you can access its settings and view information such as IP addresses, MAC addresses, connection status, and data usage for each connected device. This allows you to identify which devices are using the most bandwidth and make informed decisions to optimise your network. Additionally, you can use third-party tools and network analysis apps to gain deeper insights into your network's performance and security.

Monitor internet usage with a router

Routers are a great way to monitor internet usage, as they are the most direct source of information about what's happening within a network. All traffic flows through the router, so it's easy to monitor.

To monitor internet usage with a router, you'll first need to find your router's local IP address. This is usually 192.168.1.1 unless someone has changed it. If you're unsure, you can open a command prompt and enter 'ipconfig' on Windows, or 'ip r' on Mac and Linux. On Windows, you'll find your router's IP listed as the Gateway, and on Linux, it will be next to 'default via'.

Once you have the IP address, open your web browser and enter the IP address into the search bar, then press enter. You will then be prompted to enter your router's admin username and password. If you don't know these, check the router's documentation or look for any documentation provided by your ISP when the router was set up.

Once you're logged in, you can view your router's interface. The information you can view will depend on the vendor, but look for a list of devices or a status section. Newer routers may have bandwidth monitoring sections. From here, you can find a section that displays network traffic and start to look for which devices are using the most bandwidth.

If your router doesn't provide enough detail, you may need to use a network monitoring tool. These tools provide a range of monitoring options and can help identify cyber-attacks and network events that will affect the stability of your connection. Examples include Wireshark, SolarWinds NetFlow Traffic Analyzer, and Paessler PRTG Network Monitor.

Use third-party tools

Monitor bandwidth usage

Monitoring bandwidth usage by IP address can help organizations with limited network bandwidth to juggle the need for faster network speeds and the requirement to limit expenses. By monitoring bandwidth usage, companies can identify areas where capacity can be reduced, allowing them to optimize their network resources, boost performance, and improve productivity.

There are several ways to monitor bandwidth usage by IP address:

Using a Router:

Many routers and modems have built-in tools that allow you to see how much data each device on your network is using. To access these tools, you need to log in to your router or modem's web-based interface. You can usually find the login information in the documentation that came with the device or by searching online. Additionally, you'll need your IP address, which you can find by searching "what is my IP address" on Google. Once logged in, you can go to the router's settings to view usage information for all connected devices. Newer routers may also allow you to set usage limits or restrict access to certain websites.

Using an ISP's Home Network Management App:

Your Internet Service Provider (ISP) may offer a home network management app that allows you to view data usage, set usage limits, and set up parental controls. These apps often include features for managing your WiFi network, such as setting up guest networks or scheduling WiFi downtime.

Using Third-Party Internet Monitoring Tools:

You can use third-party tools, such as GlassWire, which runs on your computer and monitors your internet usage in real-time. It provides detailed information about data transfers, including which websites and applications use the most data. GlassWire also includes alerts for data limits and the ability to set usage limits for specific devices or applications.

Using Bandwidth Monitoring Software:

Advanced bandwidth monitoring software, such as NetFlow Analyzer, provides visibility into wired and wireless devices and their interfaces. It helps organizations tackle bandwidth monitoring challenges by providing interface-level bandwidth usage information, QoS traffic shaping, and traffic trends reports for optimizing bandwidth usage.

Using MSP Tools:

Managed Service Providers (MSPs) can assist organizations with limited bandwidth by offering bandwidth usage monitoring tools. These tools help identify applications and users responsible for network congestion, allowing companies to optimize their existing bandwidth. MSPs can provide insights into network connections, network devices, and software applications, helping organizations manage network traffic, internet usage, and bandwidth consumption.

Check firewall logs

Checking firewall logs can be a useful way to monitor internet usage by IP addresses. Firewalls keep logs that document how they handle various types of traffic, including source and destination IP addresses, port numbers, and protocols.

To check firewall logs on a Windows system, you can use the Windows Firewall with Advanced Security. Here's how:

• Open the Windows Firewall with Advanced Security by searching for "wf.msc" in the Start menu search box and pressing Enter.
• In the left pane, click on the "Monitoring" option.
• Click on the "Firewall" option in the middle pane.
• In the right pane, click on the "Connection Security Rules" tab.
• Click on the "Security Associations" option.
• In the middle pane, you will see a list of IP addresses that your computer has accessed through the Windows Firewall.

It's important to note that this method will only show IP addresses accessed through the Windows Firewall. Any IP addresses accessed outside of the Windows Firewall will not be included in these logs.

Additionally, you can use firewall logs to help identify malicious activity. For example, if you notice repeated unsuccessful attempts to access your firewall from a particular IP address, you may want to block all connections from that IP address.

Block websites

Blocking Websites

Blocking websites can be done in several ways, depending on the level of restriction and security you require.

Using a Router

The simplest way to block websites is by accessing your router's settings. First, you need to find your IP address, which can be done by searching "what is my IP address" on Google. Next, enter the login credentials for your router. If you don't know these, check the documentation that came with your router, or try the default credentials: "Admin" or "admin" for the username, and "Password" or "1234" for the password. If these don't work, you can reset your router and set a new password.

Once you have accessed your router's settings, look for a "Content Filtering" option, where you should be able to select "Block Sites". Here, you can enter domains or keywords that you want to be blocked. You can also schedule specific times when access to these sites is restricted. Additionally, you can add trusted IP addresses that will not be subject to these restrictions.

Using a Proxy Server

Proxy servers act as intermediaries between you and the internet. When you use a proxy, your internet request first goes through the proxy server, which then connects to online resources. This hides your real IP address and provides enhanced anonymity. Proxy servers are typically free and can be useful if you need to hide your IP address for a single use on a particular website or app. However, they may be incompatible with certain networks or your ISP, and they may also cache sensitive information such as usernames and passwords.

Using a Virtual Private Network (VPN)

A VPN is another effective way to hide your IP address and encrypt your online data. When you connect your devices to a VPN, they appear to be on the same network as the VPN, and your internet traffic data is sent to the VPN via a secure connection. This makes your IP address private and hidden. VPNs are recommended for anyone looking to improve the security of their devices, especially when using public Wi-Fi. While there are free VPNs available, paid options tend to offer stronger security features.

Using the Tor Browser

The Tor browser is a free web browser that blocks tracking and clears your cookies and browsing history when you leave a website. It replaces your real IP address with a different one, and it encrypts your information three times for added security. However, it may noticeably slow down your internet connection.

Using a Mobile Network or Public Wi-Fi

Changing to a mobile network or connecting to public Wi-Fi can also change your IP address, making your traffic less traceable. However, these methods will slow connection speeds, use up your data plan, and may not encrypt your data.
