This guide is about IP addresses, those…

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

Preamble

• 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 this 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 (although it is possible to proceed without a dedicated IP address to install an SSL certificate).
• Here are the main advantages:
  • Configuring a PTR entry or reverse DNS on dedicated IPs is useful, especially for installing 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 linked to websites sharing the same IP address.
  • Ease of configuring certain technical aspects.
  • A dedicated IP can improve a website's referencing (although there are differing opinions among SEO specialists).
• Attention: Infomaniak does not allow access to websites via HTTP(S) by IPs (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 issues directing web traffic to a defined port, refer to this other guide.

Blocking the IP address (Internet connection)

If you can no longer access…

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

… or if you unfortunately performed this type of operation:

• repeated unsuccessful connection attempts via FTP, SSH, or 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 following the banning of the IP address (banip / ipban) of your Internet connection.

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

Permanent Unblocking (IP on Whitelist)

With a Cloud Server, you can request to permanently authorize the IP address in question 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 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 from this IP.
