Resolve an IP address issue

This guide is about IP addresses, including:

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

The benefits of a dedicated IP for a website

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 that 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 SSL certificate activation (although it is possible to proceed without a dedicated IP address to install an SSL certificate).

Here are the main advantages:

• configure a PTR entry or reverse DNS on dedicated IPs, useful especially for setting up a mail server as some email providers verify the PTR record before accepting emails sent from a server
• better connection stability
• reduced risk of bad reputation associated with websites sharing the same IP address
• easier configuration of certain technical aspects
• a dedicated IP can improve a website's SEO (although there are differing opinions among SEO specialists)

Add a dedicated IP to the website

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

In case of issues if you redirect web traffic to a specific port, read this guide.

Blocking the IP address (Internet connection)

If you can no longer access:

• all your email addresses you own with Infomaniak (which usually work fine) and this with email software from the same 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 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) from your Internet connection.

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

Permanent unblocking (IP whitelist)

With a Cloud Server, you can request to permanently allow the concerned IP address 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 attacks originating from this IP; attacks or malicious access attempts from this address will no longer be automatically blocked by 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 attack originating from this IP
