Hey Friends! We're Whoisology
Whoisology is a searchable domain name reverse whois / ownership database with over half a billion individual domain name records that are updated pretty regularly. Reverse whois is used for cyber crime investigation / InfoSec, corporate intelligence, legal research, business development, and for good ol' fashioned poking around.

Your Job Is Serious. Data Is Boring. Look A Monster! ->
Sifting through data can be incredibly hard. We took time to figure out how we could make massive amounts of legally mandated public data digestible. We've succeeded. Domain name whois lookup data has always been publically available, but now it's actually usable.

Over 500 Million Whois Records Are Worth Dealing With A Couple Monstrously Bad Puns
And one monster joke.
Q: Why are monsters fingers never longer than 11 inches? A: Any longer would be a foot!
Yeah ... we went there.

People Dig Us... Really... You Make Us Blush...
We constantly receive emails from people sharing stories of how big data was used in the trenches, it's inspiring. You guys are the ones who are doing the really interesting things. We're just the folks in the backroom stitching your cape and filling the gas in your car, we may or may not be reading comic books at all other times.

But ... Some People Don't Dig Us
We get it. We're a visible example of what has always been available and it can be a touch unnerving at times seeing behind the curtain.

Remember, We're Not A Standard ... Regular ... Boring Whois Lookup Site
If you're looking for the current owner of a domain name use iWhois.com (our regular ... yet unique like a snowflake whois site.)

We're also not the folks who can update your whois information. You do that where you bought your domain name!
No need to tell us once you update it either, we update all the data on the site at the same time every few months.

Go Ahead, Take A Look Around
We've worked hard to build Whoisology. We want you to look around and use our site. In fact, basic usage of Whoisology is free! We want you to understand what we offer and the real value you can gain by using us. Have custom needs? Just reach out, we can help.

Choose; But Choose Wisely
Thank you for flying (metaphorically) with Whoisology. We know you have very few choices for data like ours, but we still work hard to provide unsurpassable data and user experiences. True, bears and monsters aren't overly 'serious' but our data is serious. Plus cartoons are still better than cliched stock photos. (we almost went with women laughing alone with salad)

Don't Feed The Animals
We can't be everything to everyone ... and that's ok. For most people what we offer is more than enough. We offer our clients great bang for their buck, or couple bucks, maybe the cost of coffee, or a nice dinner, but usually not much more than that. You could pay more, but why would you?
