DNS Query tools

nslookup - user friendly output. However, it is not as good as dig and host.

nslookup  node18.linux.class.
nslookup  192.168.5.38

dig - very verbose output.

dig  unisys18.linux.class.
dig mx unisys18.linux.class.
dig txt unisys18.linux.class. 
dig -x 128.6.238.19
dig txt engsoft.rutgers.edu. @128.6.224.114

host - user friendly output.

host 128.6.238.19
host -v 128.6.238.19
host -t mx ceramics.rutgers.edu.
host -t txt ceramics.rutgers.edu.
host -v -t txt ceramics.rutgers.edu. 128.6.216.19
