I think that there has been some fuzzy thinking on this thread. :)

There is no way that the command above could possibly work. The -6 
option to host means "use IPv6 transport to make this request." The 
specification of 8.8.8.8 at the end of your line tells host to use the 
name server at that IPv4 address. So no possible way that could work.

If you are trying to look up the PTR record for the address 
2001:5c0:1000:b::599b just leave out the -6 and it will work fine. If 
you are trying to do something else, let us know and we'll try to help 
you with it. :)
