'dig -t any ...' question

Hi all,

please take a look at the below reported commands I issued from DNS
(BIND 9.2.1 on Red-Hat 7.3) and the output I got
Briefly, I issued:

# dig -t any ericsson.com
# dig -t mx ericsson.com
# dig -t any ericsson.com

and I got different output for the dig -t any ericsson.com commands.
So, which is the way the 'dig -t any' command works?
Thank you all.
