You do not need to control the in-addr.arpa space to have your ISP
setup a proper DNS PTR record for your Internet connected host(s). I
have never once had any ISP tell a client that they would not set a DNS
PTR record for them upon request, to point to a specifc DNS A record
that matches the IP address they want a PTR record for.
Well, that is, as long as the IP range that the client is on is not
with a 'non-reversable' IP range (i.e. Dynamic cable/dsl/adsl/dialup).
