Do you use Domotz along with your Fingbox? Also, the requests which are being made are reverse DNS lookups which by default for Fingbox users so Fingbox can provide more security to network. If you want, you can disable the reverse DNS lookups.Here is how to do that:
1. Open the Fing App
2. Click on the avatar of you in the upper right hand corner under the clock. This will open Account and Settings.
3. Click on 'App Settings'
4. Click on on the green enable beside 'Reverse DNS Lookup'. This will disable this feature.
5. Make sure that 'Maximum network size' match your network size based on the number of devices in the house. Normally it should be a /24 size.6. Click on <-- to return to Account and Settings
7. Click on <-- to return to the Device, Network, and People tab

Thanks all. I'm happy to see this topic posted as I'm about to build, install, configure and deploy a pi-hole on my home lan as well. It'll be interesting to see the results. I'll report back here with my own findings regarding the DNS question. Thanks again.
Have DSL and not VDSL or ADSL-2... So its not by the previous US definition "Broadband"
Used to have a device called the Ad-Trap until the vendor basically went AWOL.. Pretty sure they are completely out of business...
One piece of advice, do not go over board on the Blocklists. Start off with the default, recommended list that shows during the initial install. Use that setup for a little bit (you may need to add a few things to the Whitelist over time) and see if there is something else you want to block. If you go wild to begin with and start installing every Blocklist you can find, you will spend a lot of time walking it back or adding domain after domain to the Whitelist. This advice does not apply if you are approaching the Pi-Hole from an anti-phishing/malware angle; you will have to be a little more heavy handed to keep the ever changing lists up to date, but this is overkill for the average user.
A good test site for your new Pi-Hole setup is dailymail.co.uk, it is so rampant with many different types of ads that it is a great location for fine tuning. BTW, I consider that site almost complete garbage and am not a fan of tabloids, but it is a reliable test site.
A quick note on the original post regarding the FingBox... I have deployed the Domotz box, and while not the same device there are similarities, during the 24 hour period for 8/27, that box bounced through the Pi-Hole 131798 times.

I went went with the default black lists and ended up white listing a few sites and have had no problems whatsoever.
This will let other members know they can find a good resolution in this thread too.

Fingbox does reverse DNS queries by default. In computer networks, a reverse DNS lookup or reverse DNS resolution (rDNS) is the querying technique of the Domain Name System (DNS) to determine the domain name associated with an IP address – the reverse of the usual "forward" DNS lookup of an IP address from a domain name.
If you have disabled the Reverse DNS requests and have enabled the Slower Network Discovery then the number of reverse DNS queries will reduce but some queries will take place.
After making changes, do you see any change in number of DNS queries?
