What are the connection ports
Every time we connect to the Internet, between the devices we use, such as a mobile phone, computer or any other, information is sent to the router. This exchange of data allows us to access the website or any online service.
The router now has multiple ports with which he can organize information. There are thousands of them, and some of them are open as standard, and most are closed. There is certain information that will pass through a particular port, so whether it is open or closed will affect the speed.
Routers have a range of ports from 0 to 65535 … Thus, there are over 65,000 different ports. There are three different blocks. The first one goes from 1023 to XNUMX, these are ports mainly reserved for the operating system and various basic functions.
Another block that is really important for programs is the block that goes from port 1024 to port 49151. These are the blocks that will use the various applications we install, or any online game. Sometimes when installing something, for example a game, it automatically opens the necessary ports or asks for permissions to do so.
The last block is the one that goes from port 49152 to port 65535, which is the last one. They allow specific applications to connect to servers. These are known as dynamic or private ports and are used for P2P connections.
Check open ports with You Get Signal
There are different methods and tools to help you check which ports we have open in our connection. This will let us know if the ones that we need for a particular game or program are closed and we need to open them, or if they are already configured correctly. One of these options is “You are receiving a signal.”
You receive a signal this is a web page that shows us information related to our network. This data also includes a section on the ports used. This is very useful if we want to quickly and easily see if a particular one is open.
To use it, we have to enter its Honest Sign website. You don’t need to install any programs, everything is intuitive. There we will find the section corresponding to the open ports.
If we click on It port forwarding tester will take us to a page to check if a specific port is open. Here we will need to specify the public IP address that auto-populates us, as well as the port we are interested in, and click Check. You Get Signal will provide us with information.
On the right side we have list with main ports that users usually search for. For example, we will see 21 which uses FTP, 22 which corresponds to SSH, 5900 for VNC, 25565 for Minecraft …
The process of determining whether it is open or not takes only a few seconds. As soon as we click on Check and it starts to parse it, it will show us a message indicating that this port is open or closed. From there, no matter what we have, we can go to configure the router and close or open it. We can do this with any port that interests us.
What is the use of opening ports
After explaining that router ports there really is, let’s talk about why it might be interesting to open them. We have seen that there are tens of thousands of them, so logically there is no need (or recommended) to open all of them. But yes, sometimes it is important that something is revealed.
One of the most common reasons to open ports on a router is to play online … Video game consoles use a number of specific ports, as well as video games that we install on our computer and have access to the Internet.
These games will need to connect to remote servers in order to be able to play online with other users. In order for the connection to run smoothly and to avoid breaks, it is sometimes necessary to open certain ports to be used.
Increase your download speed
Another very common reason is the ability to improve your download speed. This is especially important when we are going to use P2P applications to download or upload files. Each program will use certain ports on the router, which we have to open to slow down the speed.
To open those that correspond, we need to be informed in advance. You need to know which ones they are going to use, and thus, configure your router accordingly so as not to pose a security risk.
Use video calling software
Video call applications , just like games or downloadable programs, you will need to open certain ports for optimal performance and make the most of your connection so that there are no drops.
For example, we are talking about Skypewhich should open the appropriate ports for the connection to be as good as possible and to have a fluid communication. It’s the same with any other similar program.
Access to other devices
On the other hand, you may also need to open ports to the ability to access a specific device that we are connected over the network or remotely. This will allow us to reduce the number of problems and prevent your work from slowing down.
We can name, for example, the server we are trying to connect to. We may need to open ports for this connection to work properly.
In short, with You Get Signal, we can easily check if we have a specific router port open or not. It is a free online service that we can use on any computer to receive this type of information and set up the connection correctly.
