Ok, I checked the FAQ, should have done that in the first place and I see that 
it says I should setup my own empty zone like this in my named.conf:
zone "168.192.IN-ADDR.ARPA" {
           type master;
           file "empty";
   };

The faq then goes on to say:

   empty:
   @ 10800 IN SOA <name-of-server>. <contact-email>. (
                  1 3600 1200 604800 10800 )
   @ 10800 IN NS <name-of-server>.

That is where I'm confused as to what to place in the <name-of server>, and so 
forth. Using the example dig @prisoner.iana.org hostname.as112.net any, that 
is shown at http://public.as112.net/node/7 I get:

; <<>> DiG 9.4.1 <<>> @prisoner.iana.org hostname.as112.net any
; (1 server found)

;; QUESTION SECTION:

;; ANSWER SECTION:
hostname.as112.net.     15      IN      SOA     rfc1918.sth.netnod.se. 
hostmaster.netnod.se. 2002052700 28800 7200 604800 86400
hostname.as112.net.     15      IN      NS      blackhole-1.iana.org.
hostname.as112.net.     15      IN      TXT     "See http://as112.net/ for 
more information."
hostname.as112.net.     15      IN      TXT     "Autonomica" "Stockholm, 
Sweden"

;; ADDITIONAL SECTION:
blackhole-1.iana.org.   3600    IN      A       192.175.48.6

So should this @ 10800 IN NS <name-of-server>. be "blackhole-1.isna.org"?

And this @ 10800 IN SOA <name-of-server>. <contact-email> 
"rfc1918.sth.netnod.se"? And "hostmaster.netnod.se" as the contact-email? Or 
am I misunderstanding how this is supposed to be written?
