This is grossly misleading.  Here's the historical graph showing <100
installations of libdnet until early 2011:
http://qa.debian.org/popcon-graph.php?packages=libdnet

The increase in 2011 is not a sudden resurgence of interest; it comes
from roaraudio[1] users.  For some reason (a joke?) roaraudio has DECnet
support and its packages depend on libdnet.  You can see that the above
graph is precisely correlated with this:
http://qa.debian.org/popcon-graph.php?packages=libroar1

(And so far as I can work out, libroar1 is mostly being installed as a
dependency of an unofficial package of Xine.)

The only reason I know this is because there was a sudden spate of bug
reports on the kernel due to people getting dnet-common installed as a
recommendation of libdnet and then having their Ethernet MAC addresses
reconfigured for DECnet.
