Hey everyon! A quick and Easy DNS question.

I use DNSStuff.com 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 (whois.ripe.net).  Thus, the RIPE
Database is sometimes called the RIPE Whois Database.

ARIN Whois

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).

APNIC Whois  

APNIC is one of four Regional Internet Registries currently operating in the world. It provides allocation and registration services which support the operation of the Internet globally. It is a not-for-profit, membership-based organisation whose members include Internet Service Providers, National Internet Registries, and similar organisations. APNIC represents the Asia Pacific region, comprising 62 economies

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 pretty-sneaky-sis.mydomain.com which points to your IP.

How can you find out that I did that?  You have no idea that the record for pretty-sneaky-sis.mydomain.com even exists, without knowing the contents of my zone file for mydomain.com.

Hope that helps.

Stop suggesting silly sites that have little bearing on this question!  Where at www.dnsreport.com 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.
