Not sure I understand what the question is.
What is the relevance of your reference to 192.168.0.100 being a repeater ?
100.2.0.192 is an addess in Verizon. It looks like humax.4development.com is doing an inverse query via the pihole for 100.2.0.192 and the pihole is returning a name which it got from a public resolver.
Is humax.4development.com your HDR-T2. If so, then the question could be “why is the HDR-T2 seeking a name for 100.2.0.192 ?”
