Net::DNS::Header#format

The Net::DNS::Header#format method prints out the header
in a special ascii representation of data, in a way 
similar to those often found on RFCs. 
  
  p Net::DNS::Header.new.format
    #  +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
    #  |             18123             |
    #  +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
    #  |0|   0   |0|0|1|0|0| 0 |   0   |
    #  +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
    #  |               1               |
    #  +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
    #  |               0               |
    #  +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
    #  |               0               |
    #  +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
    #  |               0               |
    #  +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
