Updated functionality lets users request details on a subset of domains owned by a business or person.

DomainTools has released new reverse whois searching functionality, allowing users to hone in on exactly the records they’re looking for.

By reducing the number of domain records in a search, it can also make it cheaper.

The updated functionality allows you to add multiple ‘and’ and ‘or’ operators for the email address, registrant record, whois record, domain name, and extension. It lets you select text for each search indicator, which narrows down the results.

For example, a company investigating which domain names a person owns containing its trademark can enter the mark in the “domain name” field. If the company only cares about .com domains, it can add that as the extension.

You can also search the whois record based on a registration date. I think it would be helpful to also add a date range functionality for this same purpose.

By narrowing down the list of domains in a reverse whois report, users only have to pay for what they want. Reverse whois reports aren’t cheap. If a registrant has over 1,000 domains a report will set you back at least $499. Whittle the list down to 100 domains and the price drops to $99.

Why every domain owner should subscribe to a registrant alert for their domains.

If you don’t use DomainTools’ Registrant Alert service to monitor your own domain names, drop everything and sign up now (it’s free to monitor your domains). Here’s how this service has helped me in just the past few months:

1. It alerted me that one of my domains had changed to ‘pending delete’ because I neglected to renew it. That saved me from losing a valuable domain name.

2. It alerted me that four of my whois records at one registrar were erroneously changed by the registrar.

3. Just this weekend, it identified a domain I won in a drop two months ago that just changed to my name, but I realized I never got control of it (and it’s still on old nameservers). It’s a Halloween related domain, so I need to get it set up ASAP.

You get registrant alerts whenever you buy a registrant report, and domain owners can see their personal registrant report for free. You can also add other registrant alerts for a fee.

To set up your alerts, go to your DomainTools account or visit DomainTools.

Here’s a free way to get a sneak peak at a domain owner’s portfolio.

“Man, you throw a nickel around like a manhole cover.”

That comment was tossed onto my brother a few years back, and it’s now bled into me.

Cheap. Penny pinching. Sanford and Son. Call me what you will. But if there’s anything I like to keep my finger on, business-wise, it’s expenses.

And lately, that couldn’t be more true.

Down economy or not, though, I’m still buying names. Some through the drop, some by hand, but a majority have been direct – with end users who happen to own small portfolios.

Portfolio research can be tricky, though.

To perform proper research on a registrant’s portfolio, and uncover names inside a users account, DomainTools offers a powerful tool through Registrant Search. But remember, I’m cheap. And Registrant Search can be expensive (if a lot of names are uncovered). What’s needed is a baby step before a full report purchase. A free taster so to speak.

So, I racked my brain a few weeks back, to create an alternative. One that might provide a glimpse into a registrant’s account, all for free.

And I think I uncovered one…

Introducing ‘The Poor Man’s Registrant Lookup’. Take a peek inside any domain portfolio, poke around, research, etc. – all for free. No, and let me repeat, No, it won’t reveal an entire stash, but simply provides a neat slice snapshot of currently owned assets, and serves as an appetizer prior to a full report purchase.

How does it work? Well, mainly by leveraging Google. See, DomainTools allows Google to index its whois records. Meaning, if you visit mother Google, perform a “site:” command, along with a registrant’s name (or business name), Google will pump back a snapshot of all the pages within DomainTools matching that query.

Here’s an example – we’ll use good ole Frank as an example (forgive me Frank).

First, I grab the Registrant Name from any Whois search tool. For Frank, I search RumCakes.com. The name listed on the account is ‘Name Administration Inc.’.

Next, I jump to Google, and perform this search:

site:whois.domaintools.com “Name Administration Inc.”

That search, in essence, is asking Google, ‘search this domain, and pull up all results within your index with this quoted name.’

And bingo, Google jumps back and provides a snapshot. In this case, we’re looking at roughly 2,600 results including HealthClaim.com, PlumbingSupplier.com, and ShippingSoftware.com.

Neat stuff (in my opinion).

And fyi, if you encounter Google’s notification : “In order to show you the most relevant results, we have omitted some entries very similar to the 68 already displayed. If you like, you can repeat the search with the omitted results included.”

Simply click the hyperlink ‘repeat the search with the omitted results included’, and the rest of the names will appear (sometimes with even more results than originally indicated).

Happy domaining!
