Yes, if the client has the option to use another DNS server, like the IPv6 router, it will use that and will leak advertisements. Take a look at the following threads for some information on how to work around that.

> Many users have reported that frequently changing IPv6 addresses cause page load to be slow or even prevent from working at all. The issues can be fixed by updating the IPv6 address in /etc/pihole/setupVars.conf followed by a run of pihole -g. However, this solution turns out to be very inconvenient since it might be necessary to change the IPv6 address on a regular basis (maybe even multiple times a day). An alternative approach we are currently looking into is the usage of ULA addresses which…

> This behavior can be fixed by setting AAAA\_QUERY\_ANALYSIS=no in /etc/pihole/pihole-FTL.conf (you need to [create this file if it doesn't exist](https://github.com/pi-hole/FTL#ftls-config-file)). If you still see blacklisted IPv6 domains show as forwarded in your query log but don't have IPv6 enabled, you may see a false positive like the image below, where the IPv4 version of the domain is blocked, but not the IPv6 version. root@pihole:~ $ cat /etc/pihole/gravity.list | grep edge.quantserve.com 192.168.1.126 edge.quantserve.com [image] I…

Update: 2018-05-26 This problem is far less likely to happen when using NXDOMAIN or NULL blocking: [https://pi-hole.net/2018/05/18/nxdomain-and-null-blocking-with-ftldns/](https://pi-hole.net/2018/05/18/nxdomain-and-null-blocking-with-ftldns/) Pi-hole can make your network run f…
