... find some name for a DNS app thats never been used before, is funny and not too long.... well this has DNS in it and an evil touch anagram so theres that.

Well then... this is a reverse DNS scanner, which can print the output as default, json and xml. It accepts domain names, ipv4 and ipv6 as input. **

I tried to make the code a minimal secure but im a c++ noob and havent spent much time on it, so dont count on it for large scale production ^^

There is minimal input validation. The program only accepts valid IPs / domains with character limit (lib poco).

Comments in the input files preceeded by // are ignored too.**

Still here? Continue if youre mindlessly brave or the like but no warranty given ...

BUILD

There is a makefile and a CMakeLists.txt (was bored, yeah)

MAKE

make (lol)

Creates a bin dir in proj root for the bin

CMAKE

mkdir -p build cd build cmake .. cmake --build .

Bin dir in build dir

USAGE

**Usage: ./reverse_dns2 -hst <host_domain_file> -dns <dns_file> {-def | -json | -xml}

-hst <host_domain_file> == a file with ipV4 or ipv6 to reverse-dns scan

-dns <dns_file> == a file with dns servers in ipV4, ipv6, or domain format

-def == use default output

-json == use JSON output

-xml == use XML output**

test all setup: make && cd bin && ./datanamesorcery -hst ../input_sample/hosts -dns ../input_sample/dns -def && ./datanamesorcery -hst ../input_sample/hosts -dns ../input_sample/dns -json && ./datanamesorcery -hst ../input_sample/hosts -dns ../input_sample/dns -xml

Tests with valid and invalid input
