172.17.1.10:8090 – Guide Private IP Addresses and Custom Ports

The keyword “172.17.1.10:8090” may look technical at first glance. However, it simply represents a private IP address combined with a specific port number. This format is commonly used in networking, development environments, and server configurations.

In this article, we will break down what 172.17.1.10:8090 means, how it works, where it is used, and why it matters in modern networking.

What Is 172.17.1.10?

The number 172.17.1.10 is an IP address. Specifically, it belongs to a private IP address range.

Private IP addresses are reserved for internal networks. They are not accessible directly from the public internet. The range 172.16.0.0 to 172.31.255.255 is designated as private under networking standards.

This means 172.17.1.10 is likely used within:

• A local office network

• A home network

• A development server

• A virtual machine

• A containerized environment

You often see similar IP addresses in Docker containers or internal server setups.

What Does:8090 Mean?

The number after the colon, 8090, represents a port number.

Ports are logical communication endpoints. They allow multiple services to run on the same IP address without interfering with each other.

For example:

• Port 80 is commonly used for HTTP

• Port 443 is used for HTTPS

• Port 22 is used for SSH

• Port 3306 is used for MySQL

Port 8090 is not a default system port. It is commonly used for:

• Web applications

• Admin dashboards

• API services

• Development servers

• Custom backend services

When you combine the IP and port, 172.17.1.10:8090 tells the system exactly where to send traffic.

Why Is 172.17.1.10:8090 Often Seen in Docker?

In many cases, 172.17.1.10 appears in containerized environments like Docker.

Docker uses the 172.17.0.0/16 subnet by default for its bridge network. Each container receives a private IP from this range.

For example:

• A web application container might run at 172.17.1.10

• The app might expose port 8090

• Developers access it internally via 172.17.1.10:8090

This setup keeps services isolated while allowing communication between containers.

How Does It Work in Practice?

When you enter:

Your system does the following:

1. Look for the device with IP 172.17.1.10 inside the network.

2. Connects specifically to port 8090.

3. Sends an HTTP request.

4. Receives a response from the application listening on that port.

If nothing is running on port 8090, the connection will fail.

Common Use Cases of 172.17.1.10:8090

1. Local Development

Developers often host apps locally before deployment. Instead of using public domains, they access apps using internal IPs and ports.

For example:

• Backend API on port 8090

• Frontend on port 3000

• Database on port 5432

This separation keeps services organized.

2. Microservices Architecture

Modern applications use microservices. Each service runs on its own port.

Example:

• Authentication service → 172.17.1.10:8090

• User service → 172.17.1.11:8080

• Payment service → 172.17.1.12:8070

This structure improves scalability and flexibility.

3. Internal Admin Panels

Many internal dashboards run on non-standard ports like 8090. These are not exposed to the public internet for security reasons.

Administrators access them within the local network only.

Is 172.17.1.10:8090 Secure?

Security depends on configuration.

Since 172.17.1.10 is a private IP:

• It cannot be accessed from the public internet directly.

• It is protected by network boundaries.

However, risks exist if:

• Port forwarding is enabled on a router.

• Firewall rules are misconfigured.

• Weak authentication is used.

Best practices include:

• Using firewalls

• Enabling authentication

• Using HTTPS instead of HTTP

• Restricting access to trusted devices

Troubleshooting 172.17.1.10:8090

If you cannot access the address, check the following:

1. Is the Service Running?

Use commands like:

• netstat

• ss

• docker ps

Ensure the service is listening on port 8090.

2. Are You on the Same Network?

Private IPs only work inside the same local network.

3. Firewall Settings

Ensure port 8090 is not blocked.

4. Container Networking

If using Docker, verify bridge networking and port mappings.

Difference Between Public and Private IP Access

Private IPs provide safer development environments.

Why Developers Prefer Custom Ports Like 8090

Port 8090 is popular because:

• It avoids conflict with port 80

• It does not require root privileges (on Linux)

• It is commonly supported in app frameworks

• It keeps development environments flexible

Many frameworks default to 8080 or 8090 for web apps.

Final Thoughts

The keyword 172.17.1.10:8090 represents more than just numbers. It indicates:

• A private IP address

• An internal network resource

• A specific application running on port 8090

• Often, a Docker or development environment setup

Understanding this structure helps developers manage servers, troubleshoot connectivity, and design scalable systems.

Whether you are a beginner learning networking or an experienced developer working with containers, knowing how private IPs and ports function is essential.
