Steps:

1. compile && build test_ipv6.c

   $ mv Makefile_test_ipv6 Makefile

   $ make

   $ ./test_ipv6

2. compile && build test_ipv4.c

   $ mv Makefile Makefile_test_ipv6

   $ mv Makefile.ipv4 Makefile

   $ make

   $ ./test_ipv4

3. compile && build test_txt.c

   $ mv Makefile Makefile.ipv6

   $ mv Makefile.txt Makefile

   $ make

   $ ./test_txt
