This guide is about IP addresses, those…

• … assigned to websites/hosting/servers, dynamic or static, shared or dedicated,
• … assigned by your Internet Service Provider (ISP) when establishing an Internet connection to your Infomaniak product.

Introduction

• A dedicated or static IP address for a website is a permanent IP address specifically assigned to it.
• Unlike a shared IP address, which is used by multiple websites, a dedicated IP address ensures that only this platform is associated with that address.
• Dedicated IP addresses for websites are often used in cases where stability, customization, and security are important, such as server hosting, firewall configuration, or activating SSL certificates (even though it is possible to proceed without a dedicated IP address to install an SSL certificate).
• Here are the main advantages:
  • Configuring a PTR record or reverse DNS on dedicated IPs is useful, especially for setting up a mail server, as some email providers check the PTR record before accepting emails sent from a server.
  • Better connection stability.
  • Reduced risk of a bad reputation due to websites sharing the same IP address.
  • Easier configuration of certain technical aspects.
  • A dedicated IP can improve a website's search engine ranking (although there are differing opinions among SEO specialists).
• **Warning:** Infomaniak does not allow access to websites via HTTP(S) by IP (dedicated) on managed servers; you must use a domain name that points to the IP (or use the preview URL).

Add a dedicated IP to the website

To add a dedicated IP to your website, refer to this guide.

If you encounter any issues directing web traffic to a specific port, refer to this other guide.

IP address block (Internet connection)

If you can no longer access…

• … all your email addresses that you have with Infomaniak (which usually work well) and this with an email software/client from the same Internet network (that is, from the same IP address provided by your ISP)…

… or if you have unfortunately performed this type of operation:

• repeated unsuccessful connection attempts via FTP, SSH, or on access points such as the WordPress login…
• requests returning too many errors such as mass 403 errors…

… your access to Infomaniak servers may be blocked due to the banning of the IP address (banip / ipban) of your internet connection.

To unlock the situation, contact Infomaniak support by email and specify the domain concerned and especially your public IP address concerned.

Permanent Unblocking (IP Whitelisting)

With a Cloud Server, you can additionally request to permanently authorize the IP address in question so that the block does not recur under any circumstances. To do this, you must:

1. Have a dedicated IP associated with your Cloud Server.
2. Be aware that Infomaniak will no longer block potential attacks from this IP; attacks or malicious access attempts from this address will no longer be automatically blocked by the security systems.
3. Confirm by email and from a contact address associated with the account (owner or administrator) that you understand and accept full responsibility in case of an attack originating from this IP.
