Origin of reverse lookup

[alcol alcol]

ISP Have is a normale DNS zone as forward ones

they does not offer remote mainteining as you should own all subnet class and are directly downloaded from iana if I remember well.

if something go wrong with the zone ISP will have issue from tld.

in past I had a master reverse lookup maintained from me downloaded from isp becous iana can't go around the world to download and to avoid issues in download.

as are zones with so few changes isp could allow something like a cpannel to change some records.

usually reverse lookup are resolved with a standard naming with ip and isp name

if you run a mail server could be usefull if not a reverse lookup is not so much used

Subject: Origin of reverse lookup

Hi,

I had my ISP configure a reverse lookup years ago.  They say they no
longer offer that service and there is no reverse lookup for my IP.

I keep running into this old reverse lookup and do not know where it is
coming from.

When I run https://intodns.com/ it shows this reverse lookup and not the
one I just configured on my local box.

Any thoughts on how I might resolve this or find who is hosting this
reverse lookup?

Thanks!!
