First, you need to have your ISP delegate the reverse zone to your name
servers. Once that's done you need a separate PTR record in the reverse zone
for each IP number that has a host name. E.g.:

z.y.x.in-addr.arpa. NS ns1.your.domain.
z.y.x.in-addr.arpa. NS ns2.your.domain.
1.z.y.x.in-addr.arpa. PTR host1.your.domain.
2.z.y.x.in-addr.arpa. PTR host2.your.domain.
3.z.y.x.in-addr.arpa. PTR host3.your.domain.
etc.
