Deep Packet Inspection (DPI) Blocking: What is it and how can proxies help
bypass it?
Deep Packet Inspection (DPI) is a technology used by ISPs and government agencies
to monitor user traffic. If you are uncomfortable with the idea of being monitored, proxies
can help you bypass DPI and protect your privacy.
How does DPI and DPI blocking work?
This system thoroughly analyzes Internet traffic packets and acts as a surveillance tool.
DPI allows third parties to access your browsing history and the sites you visit. ISPs and
government agencies monitor users for ad research and national security purposes.
DPI blocking can occur due to censorship, for instance when a user tries to access a
banned site. Therefore, it is recommended to use a proxy.
How do proxies help bypass DPI and blocking?
Proxy servers route user requests through themselves, changing the IP address in the
process. As a result, DPI does not see the user's real IP address, but rather the IP
address provided by the proxy server.
Here is a list of proxies that can help you bypass DPI:
- Static proxies. These proxies perform well and can aid in parsing. However, they
may not be the optimal choice for bypassing DPI, as it may detect that you are
using a data center proxy.
- Proxies with SOCKS5 protocol. These proxies offer an additional layer of security
by masking the IP address and encrypting transmitted data. They are also ideal
both for P2P and for bypassing firewalls. However, their setup process can be
complicated, and the additional encryption may slow down their speed.
- Residential proxies. These proxies are highly anonymous because they show to
DPI the addresses of real people. As a result, DPI systems cannot detect that
you are using a proxy.
- Proxies with rotation. These proxies change IP addresses to prevent tracking
by DPI systems. In addition to these proxies, it is best to use SSL/TLS encryption
or SSH tunnels to bypass DPI.
To enhance protection and bypass DPI, it is recommended to use a combination of
proxies, VPNs, and Tor.
- VPN encrypts the connection;
- Tor redirects traffic through multiple nodes.
Conclusion
If you want to enhance your privacy, comfort and freedom while working on the
Internet and bypass DPI blocking, you should use residential proxies, proxies with
rotation and proxies with SOCKS5 protocol. These types of proxies can be purchased
at
Proxytunnel, which offers more than 1.5 million reliable IP addresses from 100
countries. For additional protection, consider using a combination of a proxy, VPN,
and Tor.
