How to Get the Rating of Your IP Address from AbuseIPDB with Home Assistant

This guide adds a sensor to Home Assistant that checks whether your IP address has been reported to AbuseIPDB. You'll need to register an account and obtain an API key.

Prerequisites

1. Home Assistant server
2. An IP address sensor — in this example, we use a FritzBox to get the external IP (sensor.fritz_box_7590_ui_external_ip)
3. Access to configuration.yaml

Requirements

• A self-managed VPS or dedicated server with Ubuntu 24.04 running Apache 2.4.xx.
• A registered domain name with working HTTPS (TLS/SSL). HTTP/2 and HTTP/3 only works alongside HTTPS because most browsers, including Firefox and Chrome, don’t support HTTP/2 or HTTP/3 in cleartext (non-TLS) mode.

Architecture

After multiple tries with apche2 recompiling with a different modules to support quic and http3, I simply run nginx container that will overtake only UDP traffic and forward it to the apache2 as http2 via TCP. So, no, it is not real "http3 apache2 support", but works pretty well and you do not need to change anything on your Apache2 sever.

Requirements

• A self-managed VPS or dedicated server with Ubuntu 20.04 running Apache 2.4.xx.
• A registered domain name with working HTTPS (TLS/SSL). HTTP/2 only works alongside HTTPS because most browsers, including Firefox and Chrome, don’t support HTTP/2 in cleartext (non-TLS) mode.

Step 1: Install Apache2

Per default it will be apache2 version 2.4.41 what is enought for http2 support.

Activating HTTP Public Key Pinning (HPKP) on Let's Encrypt

• Disclaimer: This might break your website, don't preceded if you don't know what you're doing.

Since the letsencrypt seems to create a new private key every time the certificate is renewed and Let's Encrypt requires you to renew you certificate once every ~80 days pinning using your certificate's SPKI is probably not the way to go. So, what should we pin then? Let's Encrypt is currently issuing from Authority X3, and using Authority X4 as a backup, so these two is a great place to start. We should also include the ISRG Root so this might support new Authorities with other SPKIs as well.

Generate HASH of Private Keys

To generate the hash of the SPKI of these certificates run the following commands
