What do IPV4 and IPV6 mean, and what is the difference between them?

What is an IP?
An IP address (short for Internet Protocol) is a unique address that identifies a device on the Internet or in a local network. The IP address is the fundamental component on which any network is built. It is a logical address used to identify the location of a device in a network. The IP addresses of certain devices can be changed by the network administrator (for example, the IP allocated to a hosting account).

What is IPV4?
"Internet Protocol version 4" (IPv4) is the fourth version of the "Internet Protocol" (IP).  It is one of the core protocols of Internet networking and was the first version implemented for production in ARPANET in 1983. Most internet traffic is still routed through IPV4, although the newer version of IP (IPV6) has been launched since 2012. The major issue with IPV4 is the exhaustion of available IP addresses, which has led to the need for the development of a new IP version (IPv6).

What is IPV6?
"Internet Protocol version 6" (IPv6) is the latest version of "Internet Protocol" (IP). IPv6 was developed by the IETF (Internet Engineering Task Force) to address the issue of IPv4 address exhaustion. IPV6 will completely replace IPV4 in the future.

What is the difference between IPV4 and IPV6?
An IPv4 address consists of a sequence of 32 bits, while an IPv6 address consists of a sequence of 128 bits. Consequently, IPV6 has many more IP addresses than IPv4.
The IPV4 notation is obtained by writing each octet in decimal form, separated by dots, while IPv6 addresses are most often written in the form of 8 groups of 4 hexadecimal digits, each group being separated by colons (:)
The coverage of IPv4 is much broader compared to IPv6 on a global scale.
There are many technical differences between the two protocols that cannot be covered in this article, but the main purpose of both versions is to identify the location of a device in a network.

Do you offer dedicated IPv6?
Yes, all hosting packages come with dedicated IPv6 included. The exception is the VPS hosting packages with the Webuzo panel, which do not yet support this protocol. VPS with cPanel or Plesk supports this protocol.

What should I choose between IPv6 and IPv4?
There is no need to choose between the two types of addresses:
-each hosting package comes with both addresses allocated: IPv6 and IPv4 (shared or dedicated)
-if a website visitor has an internet connection and a router that supports IPv6, they will connect via this protocol. If there is a network or router issue and the connection via IPv6 is not possible, the site visitor will connect via IPv4. In conclusion, the connection will be made through the visitor's available protocol.

Do I need dedicated IPv4?
Information regarding dedicated IPv4 can be found at the link Resource Usage, section Dedicated IP vs Shared IP.
