High Quality Proxies

Most often it is used on the iPhone just to bypass the blocking of access to certain resources. But also VPN is one of the most effective methods of protecting your confidential information. After all, with VPN all traffic is additionally encrypted, the provider can't read it even if it's intercepted.

It means a proxy that has no access to the Internet. It is created using special software on the user's computer. Most often it is used to check the performance of the created site or web-application.

The provider, when the user uses a VPN, "sees" only the encrypted traffic, as well as the address of the remote server to which the request is sent. But it is impossible to determine which site the user is visiting and what data is being sent.

UDP Hole Punching is a technique used to establish a connection between two devices behind NAT (Network Address Translation) firewalls. It works by exploiting the fact that some UDP packets can still pass through the NAT firewall even if the source and destination ports are the same. However, UDP Hole Punching does not always bypass NAT for several reasons:

1. Symmetric NAT: In symmetric NAT, both the source and destination ports are translated, and the NAT firewall maintains a table of active connections. If the table is not updated correctly, UDP hole punching may not work.

2. Unstable NAT: Some NAT firewalls are known to be unstable, causing them to drop packets or change their behavior unexpectedly. This can lead to failure in establishing a connection using UDP hole punching.

3. Firewall rules: Some NAT firewalls have strict rules that prevent UDP hole punching from working. For example, if the firewall is configured to block all incoming UDP traffic, UDP hole punching will not be successful.

4. Timeout: NAT firewalls have a timeout for their connection tables. If the timeout occurs before the connection is established, UDP hole punching will fail.

5. Network congestion: If the network is congested, packets may be dropped or delayed, causing UDP hole punching to fail.

In summary, while UDP hole punching can be an effective technique for bypassing NAT, it does not always guarantee a successful connection due to various factors such as NAT behavior, firewall rules, and network conditions.

To find the address of a proxy, you can follow these steps:

1. Use a proxy list: There are several websites that maintain lists of public proxies with their addresses and other details. Some popular proxy lists include proxy-list.org, proxy-list.net, and freeproxylist.ru. Keep in mind that using free proxies can be risky, as they might be slow, unreliable, or insecure.

2. Browser extensions or plugins: Some browser extensions or plugins can help you find and test proxies. For example, the "Proxy SwitchyOmega" extension for Google Chrome or Mozilla Firefox can automatically detect and test proxies from a list. You can find and install the extension from the Chrome Web Store or Firefox Add-ons website.

3. Proxy scanner tools: There are various online proxy scanner tools that can help you find and test proxies. Some popular proxy scanner tools include "Proxy-Check.com," "Proxy-Checker.org," and "ProxyScanner.io." These tools can provide you with a list of working proxies that you can use for your purposes.

4. Use a VPN service: If you need a reliable and secure proxy, consider using a VPN service. VPNs provide encrypted connections and can help you bypass geographical restrictions, access blocked content, and protect your privacy. Some popular VPN services include ExpressVPN, NordVPN, and FineVPN. Keep in mind that using a VPN may come with additional costs, but it can be a more secure and reliable option compared to free proxies.
