    Reverse DNS

    How do you setup Reverse DNS for your IPs.

    65.123.123.65

    to

    bigman.smallhost.com

    Whats the fastest and easiest solution.

    Secondly,

    Is there any software out, that will enable the "root" to assign a dedicated IP to a "customer" other than using cPANEL.

    You need to have control over your own nameservers to setup rDNS on smallhost.com on your own. If the NS's are under the control of your provider, you need to contact them to put in a PTR (pointer) entry into their in-addr.arpa zone file.

    If you control your own nameserver, you will just need to edit the nameserver zone for that domain and add a PTR entry to point to the doimain from their respective IP address.

    If you got your ips through your datacenter, they may be able to setup your RDNS IPs

    2 ways;
    you can either get full control over your rdns by telling the provider to delegate the rdns authority of those IPs to you (not common unless its an IRC server)
    or you can email techsupport and ask them to set the rdns for your ip.

    Your ISP:


    1 IN PTR 1.0.0.0.domain.com.
    2 IN PTR 2.0.0.0.domain.com.

    Your Master File:

    0.0.0.domain.com.

    In Your master File:

    1 IN PTR domain.com.



    This will tell the world that your reverse dns is CNAME'd to your nameserver. The domain that is cnamed should be your businesses main hostname.

    This is what i inform my ISP(datacenter) to add ?
    1 IN PTR 1.0.0.0.domain.com.
    2 IN PTR 2.0.0.0.domain.com.

    assumming i already have the following done ?
    in named.conf add the zone: 0.0.0.domain.com.
    in the zone file: 1 IN PTR domain.com.

    do they both work?
    sub.domain.com / domain.com / any.thing.you.can.think.of.domain.com
