Pi-hole showing weird domains on smart tv

[hnry.townshend (Henry)]

Hello everyone,

I am currently using pihole on my smart TV and I see quite lot of things
the connections every 30 seconds to srv.giraffic.com (which I believe is screenshots taken to analyse what I watch) but also, some completely ransom domains (screenshot below)

does anyone know what these domains are? is that a malware?

I would appreciate if someone could help

thanks

random domains like that without a tld are usually used to detect presence of a captive portal
