This guide details the compatibility of Infomaniak Web hosting with IPv4 and IPv6.

Introduction

• Infomaniak supports both IPv4 and IPv6, thus enabling optimal connectivity for all users.
• Only Starter (free) hosting plans and older hosting plans are not compatible: upgrade to a Cloud Server or shared hosting.
• Compatibility with IPv4 and IPv6 means that Infomaniak's hosting service allows websites to be accessible to users using both IPv4 and IPv6 addresses.
• This ensures that your site can be visited by all types of devices and networks, providing an optimal experience for your users, regardless of the protocol they use to connect to the Internet.

IPv4, or Internet Protocol version 4

This is the first version of the Internet protocol, widely used since the 1980s. It uses 32-bit IP addresses, which allows for the identification and location of devices connected to the Internet. However, with the depletion of IPv4 addresses, it became necessary to develop a new version (read more below):

• Example of an IPv4 address: 192.168.0.1
• In this example, the IPv4 address consists of four groups of numbers separated by dots…
  • Each group can contain a number from 0 to 255.
  • The address 192.168.0.1 is often used to represent a local IP address in a private network.
• Find the IP address of your website: refer to this other guide…
• Obtain the public IP address of your current Internet connection: https://chk.me/ip

IPv6, or Internet Protocol version 6

This is the latest version of the Internet protocol introduced to solve the problem of IPv4 address exhaustion. IPv6 uses 128-bit IP addresses, offering a virtually unlimited address space. It also offers improved features such as security, quality of service, and automatic address configuration:

• Example of an IPv6 address: 2001:0db8:85a3:0000:0000:8a2e:0370:7334
• In this example, the IPv6 address consists of eight groups of numbers and letters separated by colons…
  • Each group can contain a hexadecimal number from 0 to FFFF.
  • The IPv6 address is much longer than the IPv4 address, thus offering a much larger address space.
