The problem is with your ISP's servers.  They don't have
93.97.209.in-addr.arpa zone installed on them.  Since you're using RFC
2317-style delegation, even your local server depends on the parent domain
in order to do reverse lookup of its own address, because it needs to go
through the CNAME records that are supposed to be installed in the parent
domain.
