    I used Pingdom's DNS health checker and got that under "Nameserver" & "SOA".

    "The PTR record for the address points to an unknown host name."

    If the PTR record/reverse DNS points to an unknown host name do I really need to care for that. I mean can this create problems? How can I fix this?

    Yes, there are many isp's such as AOL that verify a reverse ptr before accepting emails.

    The current listed company at arin or the web host will need to be contacted to add the proper hostname for the ip in question.

    Whomever is in charge of your DNS can fix this for you by creating PTR records for your host records.

    The host that controls the IP must set the reverse PTR record with their DNS.

    You can NOT control the PTR unless your the customer/holder of the IP at arin.

    Contact your provider and give them the URL that you use to test with Pingdom
