Understanding TeamViewer’s Architecture
Before we dive into the IP addresses used by TeamViewer, it’s essential to understand how the software works. TeamViewer uses a client-server architecture, where the client is the software installed on the user’s computer, and the server is the TeamViewer infrastructure that facilitates connections.
When a user initiates a remote connection, the client software sends a request to the TeamViewer server, which then establishes a connection between the client and the remote computer. This connection is facilitated through the internet, using a combination of TCP/IP protocols and TeamViewer’s proprietary technology.
TeamViewer’s IP Address Range
TeamViewer uses a range of IP addresses to establish connections. These IP addresses are dynamically allocated and can vary depending on the user’s location and the TeamViewer server they are connected to.
According to TeamViewer’s documentation, the company uses the following IP address ranges:
- 4.79.227.0/24
- 4.79.228.0/24

What is TeamViewer and how does it use IP addresses?
TeamViewer is a remote desktop connection software that allows users to access and control other computers remotely. It uses IP addresses to establish connections between devices. When a user initiates a remote connection, TeamViewer assigns a unique ID to the session, which is then used to connect to the remote device’s IP address.
The IP address used by TeamViewer is typically the public IP address of the device being accessed. However, in some cases, TeamViewer may use a relay server to facilitate the connection, especially if the remote device is behind a firewall or router. In such cases, the IP address used by TeamViewer may be the IP address of the relay server rather than the remote device itself.
How does TeamViewer assign IP addresses to devices?
TeamViewer assigns IP addresses to devices using a proprietary algorithm that takes into account various factors, including the device’s location, network configuration, and availability. When a device is first connected to the TeamViewer network, it is assigned a unique ID, which is then used to determine its IP address.
The IP address assigned to a device by TeamViewer is typically a dynamic IP address, which means it can change over time. This is because TeamViewer uses a large pool of IP addresses to accommodate its vast user base, and devices are assigned IP addresses from this pool on a first-come, first-served basis.
Can I use a static IP address with TeamViewer?
Yes, it is possible to use a static IP address with TeamViewer. However, this requires some technical configuration and may not be suitable for all users. To use a static IP address with TeamViewer, you need to configure your router or firewall to assign a static IP address to the device being accessed.
Once you have configured your router or firewall to assign a static IP address to the device, you can enter this IP address in the TeamViewer settings to establish a connection. Using a static IP address with TeamViewer can provide more stability and reliability, especially in environments where IP addresses are frequently changed.
How does TeamViewer handle IP address conflicts?
TeamViewer has a built-in mechanism to handle IP address conflicts. If two or more devices on the same network have the same IP address, TeamViewer will detect the conflict and assign a new IP address to one of the devices. This ensures that each device on the network has a unique IP address and can be accessed remotely without any issues.
In some cases, IP address conflicts may occur due to misconfiguration or network issues. If you encounter an IP address conflict while using TeamViewer, you can try restarting the TeamViewer service or contacting TeamViewer support for assistance.
Can I use TeamViewer behind a firewall or router?
Yes, you can use TeamViewer behind a firewall or router. However, you may need to configure your firewall or router to allow incoming connections to the TeamViewer port (default port 5938). This will enable TeamViewer to establish a connection to the remote device.
If you are using a router, you may need to set up port forwarding to allow incoming connections to the TeamViewer port. This will ensure that incoming connections are forwarded to the correct device on your network. TeamViewer provides detailed instructions on how to configure firewalls and routers for use with its software.
How secure is TeamViewer’s use of IP addresses?
TeamViewer’s use of IP addresses is secure and encrypted. When a remote connection is established, TeamViewer uses end-to-end encryption to protect the data transmitted between devices. This ensures that even if an unauthorized party intercepts the data, they will not be able to access the contents of the transmission.
TeamViewer also uses secure protocols, such as SSL/TLS, to establish connections between devices. This provides an additional layer of security and ensures that IP addresses are not exposed to unauthorized parties. TeamViewer’s security measures are regularly audited and tested to ensure the highest level of security and compliance.
Can I change the IP address used by TeamViewer?
Yes, you can change the IP address used by TeamViewer in some cases. If you are using a static IP address, you can change the IP address in the TeamViewer settings. However, if you are using a dynamic IP address, you may not be able to change the IP address used by TeamViewer.
In some cases, you may need to contact your internet service provider (ISP) to change the IP address assigned to your device. This can be necessary if you are experiencing issues with your IP address or if you need to use a specific IP address for remote access. TeamViewer provides detailed instructions on how to change the IP address used by its software.
