Because without the delegation it is a broken zone. When you do a lookup for
the PTR of 165.98.241.175, you are asking your DNS server to resolve
175.241.98.165.in-addr.arpa, which will be sent to the root or forwarded
because your zone is 128/26.241.98.165.in-addr.arpa. When your ISP delegates
it to you they will create a CName record that adds another octet like
175.126/26.241.98.165.in-addr.arpa. which will be delegated to your DNS
server, you will create a PTR with IP number 175 and the server name. Then
it will not be broken. OF course this all depends on whether your ISP uses
this method.
ISP's are just as likely to delegate it to your domain name, e.g
175.241.98.165.in-addr.domain.com. Actually in many circumstances this is a
better method because many DNS hosting services don't allow access the the
reverse lookup zones and it makes it to where the reverse lookup follows you
to wherever your domain name is hosted.
