Origin of reverse lookup

[techlists at phpcoderusa.com]

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!!
