Dynamic IPv6 prefix changes force daily manual client updates in persistent client list

[thewolfwood]

Prerequisites

• I have checked the Wiki and Discussions and found no answer

• I have searched other issues and found no duplicates

• I want to report a bug and not ask a question or ask for help

• I have set up AdGuard Home correctly and configured clients to use it. (Use the Discussions for help with installing and configuring clients.)

Platform (OS and CPU architecture)

FreeBSD, ARM64

Installation

GitHub releases or script from README

Setup

On a router, DHCP is handled by the router

AdGuard Home version

v0.107.57

Action

Added client ipv6 suffix as client identifier (::[fixed_part])

Proposed Solution

Implement either:

• Pattern matching for client suffixes (::[fixed_part])
• MAC-based IPv6 client identification without DHCP dependency

Expected result

Persistent client identification through suffix wildcards or MAC binding

Actual result

Requires full IPv6 address updates daily due to ISP prefix rotation
