### Issue Details

* **Version of AdGuard Home server:**
* v0.107.2
* **How did you install AdGuard Home:**
* Curl command on GitHub
* **How did you setup DNS configuration:**
* AdGuard Home does DHCP
* **CPU architecture:**
* i386
* **Operating system and version:**
* Debian 11

### Expected Behavior
I've enabled DHCP on AdGuard Home, it properly leases IPv6 addresses to clients and the clients are using AdGuard Home for IPv6 DNS requests, however they're not being blocked and not showing up in the query log

### Actual Behavior
Ads are not blocked, DNS queries aren't logged.

### Additional Information
IPv4 & IPv6 is assigned statically to the machine hosting AdGuard Home, DHCP is disabled on router and enabled inside AdGuard Home, clients are leased IPv6 addresses and DNS propagates correctly for IPv6 because I can compare the IPv6 on AdGuard Home to the IPv6 for DNS on devices and it matches.
