libconfig library

Building and running

$ cmake .
$ make

Testing

You can test Proxy work using program like dnslookup:

$ dnslookup github.com 127.0.0.1

It will send single query response to our DNS server and, if succeed, receive DNS Response with github.com IP.

Also you can see speed of DNS server using dnsperf:

$ dnsperf -s 127.0.0.1 -d test-list.txt

It will send many Queries Per Second to our local server from test-list.txt list with queries.
Also you can set 127.0.0.1 as your system DNS resolver in /etc/resolv.conf.
