    Hello people,

    A few days ago I rented a space in a datacenter and 8 IPs. Right now, when I "host" or "nslookup" them, the reverse address is pointing to another place...

    root@test1:/# host 190.183.254.105
    105.254.183.190.in-addr.arpa domain name pointer host-105-254.avalanchehosting.net.

    What can I do with this? I think that I have to change something for all mi ip range... but where? because it is ou tof my control...

    Another thing... how do I know if I can or not manage the reverse zones for my ips? what I have to do? my IPs are public and statics...

    Thanks in advance

    Please ask your ISP if they have a web interface where you can manage your reverse records yourself. Otherwise you'd have to ask your ISP to change the reverse records for you.

    Only the owner of the IP range can change this (or me using a control panel if it is possible) ?... is not possible to manage reverse with my dns server (i have 5 public/static IPs) ? This is a new world for me xD

    Is recommended that every server has its own reverse? or just for email servers?

    Thanks falko!

    Usually yes, but some ISPs allow you to manage your reverse records through a web interface.

    Normally your ISP should set a reverse record for all your IPs; as long as there is a reverse record that does not look like the server is on a DSL line (sometimes you have reverse records like adsl357452.bla.someisp.net which might be blocked by blacklists because it looks like you are on a DSL line) everything should be fine. However, I prefer to set my own reverse records because they are easier to remember.
