    You need to inform your Datacentre, Ip holder who lease the Ip from ARIN, APNIC, LACNIC depending on your region.

    Hello :)

    Reverse DNS uses pointer records (PTR) to convert IP addresses into domain names. This is the opposite of forward DNS, which uses A records to convert domain names into IP addresses. This is documented at:

    RDNS for Bind

    However, typically you must consult with your hosting provider or data center so they can setup the reverse DNS for you.

    Thank you.

    SWIP (Shared WHOIS Project) is the process that ISP's use to make their submissions of IP space reassignment information to WHOIS.

    Thank you.

    Thanks Michael.

    Then x ISP ABC = owner of range 22.22.22.1 to 22.22.22.256 (by example)

    Then when a little company rent a server,
    the ISP ABC reassigned [WHOIS/INFO OWNER]
    of range 22.22.22.1 to 22.22.22.5
    becouse IPs from 22.22.22.1 to 22.22.22.5 now is used by
    "little company"

    This is SWIP?

    Thanks Michael.

    BIG Company = "They talk with ARIN directly"
    Little Company = "request SWIP to BIG ISP"

    Correct?
