wasabisys.com always gets N/A reply; perhaps due to absurd reply that can’t be handled?

Versions
- Pi-hole: 5.18.1
- AdminLTE: v5.21
- FTL: v5.25.1
Platform
- OS and version: DSM 7.2.1-69057 Update 3
- Platform: Synology
Expected behavior
I should be able to resolve wasabisys.com. to an IP address. When I set my machines to directly hit up 8.8.8.8 or 1.1.1.1 it succeeds.
Actual behavior / bug
However, when I set my machines to use my Pi-hole as the DNS server, trying to resolve wasabisys.com. times out. It shows up in the Pi-hole log as an N/A reply.
Steps to reproduce
Steps to reproduce the behavior:
- Set up a computer to use Pi-hole
- Open a web browser
- Attempt to navigate to
wasabisys.com. - Watch it timeout
Debug Token
Additional context
FYI, if you do > dig @8.8.8.8 wasabisys.com you’ll note that wasabisys.com. has 42 (!!!!) different A records, and the received message is 714 bytes. That’s an absurdly big reply. Is Pi-hole correctly handling that?
I'm not able to reproduce the issue using the latest Pi-hole image:
rdweb@pi4:~ $ dig wasabisys.com @192.168.0.200
