SOCKS5 was derived from SOCKS which actually means Socket Secure; it is an abbreviation for SOCKetS. A SOCK is an internet protocol that acts as a network packets router through a proxy server between a server and a client. This SOCKS is an Internet Protocol (IP) that allows client-server applications to transparently use a network firewall’s services. The only purpose of SOCKS is to transfer from a client’s data to a server. With that, anonymity of this proxy type is really evident.
Moreover, there are two versions that came to the market – SOCKS4 and SOCKS5. SOCKS4 is an extension that fixes a common problem. On the other hand, Free SOCKS5 Online Proxies protocol is in RFC 1928 and is an extension of SOCKS4. SOCKS5 proxies support UDP that extends the addressing scheme encompassing V6 IP addresses and domain name. Also, it extends the framework including provisions in generalizing authentication schemes that are believed to be strong. SOCKS5 connects clients by including a list of authentication methods. Client connects and sends a greeting which includes a list of supported authentication methods. It works by choosing one method, yet if a failure response was sent, none of the methods will be accepted. With SOCKS5, several messages are now allowed to be passed between the server and the client but this will depend on the method chosen for authentication.
Free SOCKS5 Online Proxies works at a 5-layer OSI model which is the session and intermediate layers between the presentation and transport layers. Furthermore, SOCKS5 is different from SOCKS4 since the first one is a more advances proxy. Below are the things that made SOCKS5 different from SOCKS4:
– UDP proxy support
– DNS requests through the proxy
Hence, the two, SOCKS4 and SOCKS5, are clearly different. With this comparison, it is obvious that SOCKS5 is way better yet it doesn’t mean that version 4 is that bad.
