how to setup class b ?

[Mark_Andrews at isc.org]

	Is this any clearer?

	172.27.X.Y become Y.X (reverse order) in the reverse zone.

	Mark

Forward:
$ORIGIN	example.
@	IN	SOA	ns1.example. hostmaster.ns1.example. 1 2 3 4 5
	IN	NS	ns1.example.
	IN	NS	ns2.example.
host1	IN	A	172.27.0.1
host2	IN	A	172.27.0.2
host3	IN	A	172.27.0.3
ns2	IN	A	127.27.255.253
ns1	IN	A	127.27.255.254

Reverse:
$ORIGIN	27.172.in-addr.arpa.
@	IN	SOA	ns1.example. hostmaster.ns1.example. 1 2 3 4 5
	IN	NS	ns1.example.
	IN	NS	ns2.example.
1.0	IN	PTR	host1.example.
2.0	IN	PTR	host2.example.
3.0	IN	PTR	host3.example.
253.255	IN	PTR	ns2.example.
254.255	IN	PTR	ns1.example.
