Quoting from the web site at https://dnsflagday.net/
huh, from the 'dns illuminati' eh"
DNS hosted by
gandi.net? resolves to 3 /32's on 3 adjacent /24's.. in github's ip space, routed by
fastly.com ...
I'm sure glad the whois data for that domain is sensible too... :(
none of that particularly leaves me feeling like I should go put any data at all into the site.
