  printf "\0\1\1\0\0\1\0\0\0\0\0\0\6reddit\3com\0\0\1\0\1" |nc -vvuq1  53 |xxd


0x0001 means transaction ID. Invent one as you like
0x0100 Flag. Always this for all requests
0x0001 number of requests: always 1. because DNS RFC sucks
0x0000 Response: 0

\6 reddit The string reddit has length of 6
\3 com The string com has length of 3

then ping the last four bytes

  $ ping 0x60.0x11.0xb4.0x89
  PING 0x60.0x11.0xb4.0x89 ( 56(84) bytes of data.

Why DNS Resource Record Name is always C0 0C?

It's compression.

C00C = 11000000 00001100

First two bits means it's a pointer, b1100 = 12 bytes offset.
