pi-hole/FTL v5.3

Pi-hole FTL v5.3

on GitHub

All (@DL6ER) unless otherwise specified!

Highlights

• Upgrade RegEx engine #815
  Adding approximate matching (catch URL typos), back-references, more character classes for bracket expressions, type-specific filtering (e.g. regex only for type AAAA queries), and more. See this Discourse discussion for further details.
• Analyze EDNS(0) records #851
  We highlight the Client Subnet (ECS) feature to obtain client IPs even when they are hidden behind a NAT or a deputy DNS server. See this Discourse discussion for further technical details. This feature can be used to unveil the real IP addresses of clients even when there used to be the router's IP address for all clients (if supported by the router).
• Allow defining clients by their MAC address #762
  This allows you to use MAC addresses to automatically identify clients immediately connected you the Pi-hole. This will make the configuration for clients changing their addresses frequently (non-deterministic DHCP server, IPv6 privacy extension, non-constant ISP IPv6 prefixes, etc.) easier than before.
• Add dhcp-discover feature #883
  A new feature to actively scan all interfaces for available DHCP servers. It can be invoked using sudo pihole-FTL dhcp-discover
• Add additional pre-compiled ARMv4, ARMv5 and ARMv8 binaries #903
• Add new query retried status (12 and 13) #901
• Differentiate upstream servers by address and port #923
  This allows the statistics to tell apart servers on the same IP address running on different ports.
• Add API callback to remove DHCP leases without the need for a restart #932
  This removes an active lease from the server. Note, however, that the clients also actively need to ask for a new lease (reconnection, restart) as it may otherwise continue to use its old (even if now invalid) configuration until the lease time expires. Unfortunately, Pi-hole cannot do anything about this.
