Hey everyon! A quick and Easy DNS question.

I use fairly often to find an IP address associated with an A record.

Is there a way to find ALL (if any) A records associated with an IP Address??

many thanks

    Europe - Ripe (Whois) Database - IP Search

    The RIPE Network Management Database (the RIPE Database) contains information about

    Allocations and assignments of IP address space
    Internet routing
    Reverse DNS
    Related objects.

    The data is put into the database by those who operate IP networks
    within the RIPE region. The RIPE NCC supports the operation of the
    RIPE Database, but it is not responsible for its contents.

    The data is accessible by a whois service (  Thus, the RIPE
    Database is sometimes called the RIPE Whois Database.

    ARIN's WHOIS service provides a mechanism for finding contact and registration information for resources registered with ARIN. ARIN's database contains IP addresses, autonomous system (AS) numbers, organizations or customers that are associated with these resources, and related Points of Contact (POC).

    I know how to find a PTR record (if one is set). However, I want to be able to type in an IP Address and then see all A records associated with that IP Address... is this possible??

    this is not a quick and easy question, as you claim.

    "However, I want to be able to type in an IP Address and then see all A records associated with that IP Address... is this possible??"

    Try IPNET INFO --- it is a free program, that is about the best you will get, and no, it does not give all A records.

    Quite simply, no.

    To do that (find all A records for a specific IP), you would have to have access to all the zone files of all DNS servers everywhere.

    Here's an example:

    I add an A record for which points to your IP.

    How can you find out that I did that?  You have no idea that the record for even exists, without knowing the contents of my zone file for

    Hope that helps.

    Stop suggesting silly sites that have little bearing on this question!  Where at do you type in an IP to see A records?  No place, that's where...

    The answer to this question is a simple "No".  If you understand my above explanation, you cannot disagree.

    You really should try

    They do reverse from all the zones they know, pick an ip of a shared hosting server, you will get all the domains that registered for that ip.
