To DNS Name [Other DNS names]
|Display Name||To DNS Name [Other DNS names]|
|Short Description||This transform performs a reverse lookup via historical/passive DNS|
|Author||Roelof Temmingh (email@example.com)|
This transform queries two different 'historical' DNS databases - Serversniff and Robtex to see what other DNS names are associated with the IP Address. These databases are populated using various techniques.
The transform is useful to find co-hosted sites - e.g. the website (or MX, NS) of companyA could resolve to 188.8.131.52 and co-hosted on that IP address are www.companyB.com and/or companyAB.com. In certain cases you will find that the forward DNS entries for the resultant DNS names are is now pointing to other IP addresses (other than the supplied one). This simply means that changes have been made to DNS, and that the provider's database is keeping the old information. Sometimes this is useful (as you can see that a change was made), sometimes it is annoying.
