I am writing recursive DNS server.

It has 2 parts doing network-related work.
  one part reading requests from clients on port 53

  second part is dealing with remote servers (sending requests to them and
    waiting for replies)

i will nead 2 different protocol chains. one for parties queries and second
for parsing replies. Need i create 2 controller objects? (i think yes)
