Together, they represent a specific connection on your local computer. But what does that really mean? Let’s dive deeper.

The Magic of 127.0.0.1

127.0.0.1 is a special IP address known as “localhost.” Think of it as your computer’s home address on the internet. When you use 127.0.0.1, you’re telling your computer to connect to itself. It’s like calling your own phone number – you’re not reaching out to anyone else, just talking to yourself!

Some key points about 127.0.0.1:

• It always refers to your own computer
• It’s also known as the “loopback address”
• You can’t use it to connect to other computers

What’s the Deal with 62893?

The number 62893 in our example is what’s called a “port number.” Ports are like doors in your computer that allow different programs to send and receive data. Just like your house might have a front door, back door, and garage door, your computer has thousands of ports that can be used for different purposes.

Some important things to know about port 62893:

• It’s not a standard or reserved port
• Different programs might use this port temporarily
• The port number can change each time you restart your computer or the program
