WhoIs Lite is a lightweight desktop utility for submitting WhoIs queries. This is a tool I wrote whilst developing a more complex domain lookup/catching tool, and I keep it on my desktop to do quick WhoIs lookups. WhoIs Lite does NOT do bulk WhoIs lookups as there are several well developed tools available for this purpose, it is simply there to do quick, single, lookups.

WhoIs Lite will query the following Top Level Domains (TLDs): .uk .com .eu .net .info .org .biz .it .us .in .cn

Free Version Free, absolutely free... The free version has all the functionality of the donor version but carries a banner ad. Type in your domain, click Lookup, and the domain registration details will be displayed in the response pain. You can set your default TLD to save time if you're only interested in one, i.e. if you are only interested in .co.uk set this in options and it will be appended to the name automatically. Once your data is returned the cursor pops back to the search box ready for another

Donor Version The same functionality as the free version but no banner advert. The donor version is not constrained by the size of the advert and accordingly is sizable in both directions (the free version only sizes vertically). For £3.95 upgrade to the donor version to get rid of that annoying advert and to be able to squeeze the window to your preferred size. Download the free version first to find out how useful this tiny tool is but don't forget to come back. For £3.95 ?, thats less than the cost of a .co.uk domain from 123-reg...!
