Have you ever needed to lookup DNS on a large list of IPs?  How about parsing a security log to see where a potential threat is coming from?  Combing through the log and getting the full list of IPs can be tedious and tiresome.  And, then you still have to run the DNS checks one-by-one or write a script to do it for you.

Or, you could come to MxToolbox where we have all the cool tools…

That’s right, we’ve launched a DNS Batch Lookup Tool that does all that for you.  Available to all MxToolbox Professional users, DNS Batch Tool eliminates the time-consuming work of parsing text for IP addresses and repetitive DNS lookups.

You can find it on the main menu of the MxToolbox Professional interface* along with our premium monitors like DNS Zone Protect and MailFlow Monitoring.

DNS Batch Tool provides takes simple text as the main input.

As, you can see below, I’ve copied an entire email into the tool so I can see lookup routing information for my most recent campaign.  I could also use security logs or a pre-generated list of IP addresses.

DNS Batch Tool parses the text file and automatically extracts all the IP addresses.

Processing these IP addresses yields reverse host name, country, region and city information, AS number and AS name.

Note: you must be a paid user to access MxToolbox Professional.
