When looking at my DNS provider (Hurricane Electric), I effectively
have no PTR record. I must set one but honestly, I am far from
understanding everything about PTR.
Unless you have a unique IP, one that's always assigned solely to you,
your ISP is unlikely to set a PTR record for you. Usually, they share
addresses, one way or another (e.g. dynamic IPs) between their users,
and PTRs point to their own hostnames.
