The world of network technology can be quite confusing, right? There are so many technical terms and processes that can sometimes be a headache. One of these Concepts is PAT – Port and Address Translation, in German port and address translation. What does that mean exactly? And how does it affect our daily digital lives? I'll give you all of this erklären, so everyone can understand it!
PAT – Port and Address Translation
Um PAT To understand, let's first take a step back and look at it Basics look at. PAT is, so to speak, a helper that works in devices such as routers to get the addresses and "house numbers" of computers on our home network into public addresses and “house numbers” that can be used on the Internet. But why do we need this?
Very easily: We don't have enough public addresses for all the devices we use connect to the Internet want. PAT allows many devices to use a single public address to communicate with the Internet to communicate. It's like having a single phone line that multiple people can use to make calls at the same time.
How does PAT work?
PAT works a little like one post man. The Router takes a request for that Internet on, changes the sender address and the "House number« and sends it further onto the Internet.
Why is PAT important?
PAT is like an invisible hero of our daily digital lives. Without PAT we couldn't multiple devices at the same time with the Connect Internet - at least not without one separate public address for each device. That would be like if every person in your house needed their own phone line so they could make calls at the same time. With PAT we can avoid that and have many devices at the same time Internet connect, at no extra cost.
The technology behind PAT
Now that we know what PAT is and why it's so important, let's delve a little deeper into the technology behind it. Don't worry, I'll keep it simple!
The role of the router
The Router plays a central role in the work of PAT. It is he who meets the requirements of the devices in your Network records, changes their addresses and "house numbers" and then sends them onto the Internet. You can think of the router as a type Ăśbersetzer imagine that the messages coming from your devices are in the Internet can be understood.
What is NAT?
PAT is actually a special form of a technique called Network Address Translation (NAT), in German Network address translation. NAT is the fundamental concept that allows multiple devices to share a single public The IP address to be able to use. PAT goes one step further and allows multiple connections from different devices to be made simultaneously over a single public The IP address be able to walk.
PAT in practice
Now that we understand the technology behind PAT, let's take a look at what it looks like in practice.
Home networks
If you have one at home WiFi network then you probably use it PAT, without knowing it! Every time you with your Smartphone, Tablet or Laptop the Internet surf, you use it Router PAT to connect all these devices at the same time Internet connect to.
corporate networks
PAT is also often used in companies. PAT allows hundreds or even thousands of employees to access the Internet simultaneously without having to have a separate public address for each device The IP address is needed. This not only saves costs, but also simplifies it Network Management considerably.
Frequently asked questions about PAT
It's natural that you still have some questions about PAT. Here are some of the most common questions I get asked and my answers to them.
Is PAT safe?
Yes, PAT offers certain security, since it is the internal IP addresses and Ports of the devices in your Network hidden from the outside world. But alone it is not enough for you Network to protect completely. It's always a good idea to have extra Safety measures like firewalls and Antivirus software to use.
Can I turn off PAT?
Technically, you can set PAT in the settings of your Routers turn off. But in most cases it is not a good idea. Without PAT, you wouldn't be able to connect multiple devices to the Internet at the same time unless you have a separate public one for each device The IP address.
Does PAT affect internet speed?
Usually has PAT no significant influence on the Internet speed. However, it can be very high traffic zu delays come because the router has to process every single request. But in most Home and corporate networks is not a problem.
Conclusion
PAT - Port and address translation like on the complicated at first glance appear, but once you understand it, you realize how important it is to our daily lives digital life is. Without PAT we couldn't do it so easily and reduce your recruitment costs multiple devices at the same time Internet connection. It's one of those invisible ones Technologies, who work in the background to make our digital lives smooth and efficient.
