	For what purpose?

	BIND-8 listens to either a Unix socket or an Internet socket, for 
communications with the "ndc" program.  BIND-9 listens exclusively to 
an IP socket for this purpose.  Both programs listen exclusively to 
IP sockets on port 53 for handling DNS.

	For handling DNS?  No.  Unix sockets would only be useful on a 
particular machine for its own use, and in that case you can run a 
local resolver listening on 127.0.0.1 on port 53.

	Feel free to try adapting the code and then come back and tell us.
