I’ve done several experiments with DNS, which has lead me over the last couple of years to develop a DNS resolver tool.
By no way is it a full fledged DNS server: it implements particular features that I’ve needed for different experiments I conducted.
It can serve files, facilitate exfiltration, do tracking, answer wildcard requests, do rcode testing and also simple resolving.
Upcoming blog posts will go into more details for some of these features.
