How do I check proxies for quality? Special services will show you if your proxy is defined as quality or not.
Once we connected the proxy we went to whoer.net. With the help of this site you can evaluate the quality of a proxy. You can check what data the proxy sends. As you can see in the screenshot above the proxy has a positive rating. DNS is detected correctly and if the selected country is Russia, DNS is detected in Russia. Proxy, Anonymizer and Blacklist checks are also successful. This means the proxy is clean.
The detection of the operating system is correct – MacOS X, because the test is performed on a MacBook. Windows will be detected when checking with Windows.
Timezone data is correct. And data headers are transmitted correctly, headers from MacBook are transmitted. WebRTC also passed the test. Whoer.net – has a free online version. Anyone can check their proxies.
Another service is getipintel.net. On the basis of an advanced mathematical apparatus calculates the probability of using technologies that hide the real ip-address.
This service should check the value less than 1. Values between 0 and 0.5 make the proxy qualitative.
You can additionally check your proxy at whatleaks.com. You can use this service to find out how good your proxy protects you and if it sends the right information. As you can see in the screenshot above the result of Blacklist check is great. Proxies have positive scores on headers, hostname, useragent, time check.
Static or dynamic IP?
Every computer connected to the network has its own unique or not so unique identifier on the Internet, with which other computers can access it and respond to its requests. If there was no such address, how could the network determine which message was intended for which computer? Logically every computer should have a unique address, but the technologies developed, the number of devices increased rapidly and the free addresses began to be insufficient.
That is why different technologies were invented, that allowed using free addresses one by one for different computers and then using one address for hundreds of computers. In this article we will consider what is better – static or dynamic ip, how these addresses differ, the advantages of each option, as well as how to know what kind of address you have.
When the Internet was just beginning, each computer or server had a static IP address. This address was given to computer at first connection to network by ISP, and then it was registered in computer settings and never changed even during reboots. When addresses became scarce, several technologies were invented to solve the problem. Static addresses now cost money and are mostly used only for servers.
This is to make sure that users always have access to the server. IP is the only identifier of a computer on the network and it is the only way the computers find each other. If ip will change, you will have to change a lot of settings and wait a certain amount of time until the site or server will be assigned a new address.
What is dynamic IP add?
Since the number of devices that need to connect to the network was increasing, and the number of IPv4 addresses is strictly limited providers had to resort to various optimizations. One of these optimizations was dynamic IP addresses. It is exactly the same as a static address and the computer is fully accessible from the network. The only difference is that you get this address every time you connect to the network and each time it may be new.
This is based on the fact that users do not use the Internet around the clock, and devices are not on around the clock. Which means an ip address will be idle for a certain amount of time. To solve this problem you are given one of the free addresses, as soon as the connection breaks, this address is released and given to someone else or after a certain time. If you reconnect you will be given a new address. These addresses are handed out via DHCP. With this address you can still play online games with your friend, but you can no longer host the site, because the ip will change and the site will be unavailable all the difference between a static and dynamic ip is this.
What is NAT?
Dynamic addresses gave insufficient optimization, only a few times. This was not enough and the ISPs had to use another technology instead of dynamic addresses. That was NAT. I decided that it’s impossible not to tell about it in this article about comparing ip addresses. Many newbies read the article about dynamic ip and think – “Suppose I have a dynamic ip, well, now I’ll run the game server, I will give my IP friend and we’ll play,” but it was not there, it does not work. And why? Because now the dynamic IP is no longer used by providers. I still remember when it was like this, run the server SAMP, told a friend the IP and play.
In place of the dynamic addresses came the technology NAT, which allows you to use one ip address for hundreds of users simultaneously. It is very simple. Computers are combined into a local network provider and each computer gets a unique ip address from the range 192 or 172, which are designed for local networks. Then there is one server, which has a static IP and acts as gateway to the internet, for this local network.
When a computer sends a request to the server, the server replaces the send port with its own value and remembers that the responses on this port should be sent to such a computer from the local network. When it receives a reply, the server simply changes the port to what it was before the change, takes the computer’s local address from memory on the port, and sends it a message. But if another computer decides to contact yours externally and sends the request first, you get a problem, the server won’t know which of several hundred computers it is addressing to and nothing will work.
Is this bad for normal users? I think not. I think it’s even better. When you have a static IP, you are very easy to get to. Your IP address is recorded everywhere, so you’re easy to identify. In addition there are plenty of bots on the net trying to brute force passwords to ssh, ftp and other services, exploit vulnerabilities, and so on. If the server is specially configured to work in such an aggressive environment and is constantly updated, the home user’s computer is unlikely.
What is better?
Now let’s try to answer the question, dynamic or static ip better for your situation. If you take the server, the answer is unambiguous – static ip and no other options.
With the home computer, too, everything is simple. Static and dynamic IP is dangerous for him. For example, I have many different programs running on my computer and I need them for testing. Each of them can hide vulnerabilities and more than one. Vulnerabilities are found all the time, in Windows as well as in Linux. So here NAT is the perfect solution. You are sufficiently protected and less of the outside world can access your computer.
If you’re wondering how to know what ip is dynamic or static, that’s easy enough too. You can take your IP and try to connect to it by external ip. For example, run Apache on port 80 and try to connect to your external ip. If authentication appears instead of the expected Apache start page or there is some kind of error, then it is NAT. If your page opens – the IP is probably dynamic. You can see if it changes on reboots. But if you have not bought a static IP separately, then it is mostly dynamic. And you already know the difference between static and dynamic IP.
As for choosing the IP address for your home local network, things are a bit different. Of course, it is much easier to get an address via DHCP, but if you configure static addresses, you will, first of all, connect to the network faster, and secondly, you will always know what address a particular device has. I hope this information was helpful for you. If you have any questions about whether a static or dynamic ip is better, ask in the comments!
