This setup is described in RFC 2317.  It's also in the O'Reilly "DNS &
BIND" book in the section titled "Subnetting on a Non-Octet Boundary".

You should put your PTR records in your named.hosts file, as follows:

208.142.133.10				IN PTR	gw
208.142.133.11				IN PTR	ns
208.142.133.12				IN PTR	ns2
208.142.133.13				IN PTR	www
208.142.133.17				IN PTR	telegraph
208.142.133.19				IN PTR	ross
