If you have bind version 4, add  secondary b 194.113.40.45 CACHE.b  to your named.boot.
	Bind-9 and above, add  zone "b" in {                      type slave; file "CACHE.b"; masters { 194.113.40.45; };  }; to your named.boot
	If you use dnscache, use this: # echo "194.113.40.45" > /service/dnscache/root/servers/b # svc -t /service/dnscache/
	If you do not wish to run a secondary, you can add ; B-DNS toplevel b.                       3600000      NS    ns.b. ns.b.                    3600000      A     194.113.40.45 to your named.root (the . cache-file)
	Alternatively, you can join TINC, which has added the B Toplevel into it's root-zone file. Simpy replace your named.root file with the one supplied by them.
	Not running a namesver at all: Talk to your provider, and ask them to provide the "B-dns" to you. Refer them to this page, if they don't know what to do. Convincing your provider to join B-DNS will get you one free domain, so it's worth it.
