IPv4 VS IPv6 Proxy: What’s the Difference?

| Updated on May 8, 2024

It’s amazing, but in 2022 Internet resources are still working via IPv4, although about 7 years ago, they were talking about the transition to IPv6. This article is for those who want to understand the features and differences of proxy servers IPv4 VS IPv6.

How Does IPv4 Work?

IPv4 (Internet Protocol version 4) is the fourth major revision of the Internet Protocol, used to identify devices on the network and facilitate data transfer. It is a connectionless protocol, which does not require acknowledgment or confirmation from any of the parties involved in the communication. Instead, messages sent over IPv4 go through all the routers between the source and the destination. 

IPv4 allows a maximum of about 4.3 billion unique IP addresses, which are used to identify each device on the network uniquely. Each address consists of 32-bit numbers (such as divided into four 8-bit octets representing the network, subnet, host, and port. The network octet of the IP address is used to identify the network on which the device exists, and the remaining three octets are used to identify that device specifically. 

When data is sent over a network using IPv4, each packet containing data includes source and destination addresses so it can be routed to its destination. When the router receives an IP packet, it looks at the source and destination addresses to determine where to direct the data next. If the destination address is on a different network than the sender’s, the packet must go through several routers before it reaches its destination. Each of these routers checks the headers and forwards the packet to the next router until it reaches its destination. 

IPv4 is still widely used, but because of the limited number of IP addresses, other protocols, such as IPv6, have been developed to allow more devices to connect to the network. IPv6 expanded the address space from 32 bits to 128 bits, allowing many more devices to be connected. Despite its limitations, IPv4 remains the standard protocol used in most networks worldwide. 

By understanding how IPv4 works and recognizing its components, you can more effectively troubleshoot network problems or configure routers that use it. Also, if you’re planning on moving to an IPv6 network in the future, understanding how IPv4 works are essential. By understanding this protocol and its components, you will be able to maximize the security and efficiency of your network.  

How Does IPv6 Works?

IPv6 (Internet Protocol version 6) is the successor to IPv4, designed to overcome the address space and host limitations of its predecessor. It allows a much larger number of IP addresses than IPv4 – about 340 trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion, which is enough for all devices connected to the Internet for centuries. 

Unlike IPv4, IPv6 is a connection-oriented protocol, which means that it uses a kind of “handshake” to ensure the successful transmission of data packets between source and destination. Each party acknowledges the existence of the other party before transmitting data. It also provides end-to-end security through encryption and authentication. 

IPv6 addresses are 128 bits long and are represented as 8 groups of 4 hexadecimal numbers (for example, 2001:0DB8:0000:0053:0000:0000:9C31). Typically, the first 48 bits identify the network, and the remaining 80 bits are used to identify specific devices on that network. 

In general, IPv4 and IPv6 are two different protocols that are used to facilitate data transmission over the Internet. While IPv4 offers enough IP addresses for everyday use, IPv6 is quickly becoming more popular due to its larger address space and improved security features.  Regardless of which protocol is used, both play an important role in making the Internet accessible. 

Also, one way to help increase the security of data transmission over an IP network is by using socks5 proxy. Socks5 proxies are specifically designed for use with both IPv4 and IPv6 networks, and they act as intermediaries between a client computer and the Internet. 

The choice between the two protocols depends on the specific needs of an organization or individual, but in general, IPv6 is becoming increasingly preferred because of its larger address space and improved security features. Regardless of which protocol is used, both continue to play an important role in Internet accessibility and security. 

What Will People Choose in 2022, IPv6 or IPv4?

By 2022, it is expected that IPv6 will have become the more popular protocol, as IPv4 addresses are running out and cannot be reused. Many internet service providers already offer dual-stack technology that allows devices to use both protocols, allowing them to take advantage of the larger pool of IPv6 addresses.  If you are looking to check which protocol your connection is using, a free proxy checker can help. The free proxy checker will scan your network and provide information on the type of protocol being used, its speed, and other related parameters.  


In conclusion, IPv4 and IPv6 are two different protocols that are used to facilitate data transmission over the Internet. Both protocols have their unique advantages and disadvantages, with IPv6’s increased address space and improved security features making it increasingly popular. Regardless of the choice of protocol, both are essential to the availability and security of the Internet.
