How do I do reverse ipv6 dns lookup in a script,
in particular using /usr/bin/host utility ?

Thanks

You could put results into an array and parse it.
You can use a while loop to read command,
you can pipe command into a file and use a while
loop to read the file.

You can use "set" to parse a line.
man set (then man man to find set builtin)

You can modify IFS to parse fields out of a word.

man host
to get command line arguments for ipv6.
