This guide is about IP addresses, including…

• … those assigned to websites/hosting/servers, dynamic or static IPs, shared or dedicated IPs,
• … 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 that is 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 hosting servers, configuring firewalls, or enabling SSL certificates (although 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 installing a mail server, because some email providers check the PTR record before accepting emails sent from a server.
  • Improved 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).
• Note: Infomaniak does not allow access to websites via HTTP(S) using dedicated IPs 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, please refer to this guide.

If you are experiencing issues when directing web traffic to a specific port, please refer to this other guide.

Blocking the IP address (Internet connection)

If you can no longer access…

• … all your email addresses that you have with Infomaniak (which usually work fine) and this using an email software/client from a single Internet network (i.e., 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 a large number of 403 errors…

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

To resolve this, contact Infomaniak support by email, specifying the domain concerned and, above all, your public IP address.

Permanent unblocking (IP whitelisting)

With a Cloud Server, you can request that the IP address in question be permanently whitelisted so that the blocking never happens again, regardless of the situation. To do this, you must:

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