who it works

dnsdist supports Lua via LuaJIT, so we can use string.match for our pattern matching.

string.match(reply, "%d+%.%d+%.%d+%.%d+")

then we access the FFI library, which allows calling external C functions and using C data structures from pure Lua code. And with the help of INET_PTON, we can validate the IPv4 from the hostname!


The entire configuration is about 42lines!!! You can check it here: [dnsdist.conf](dnsdist.conf)
