Whois on widget

PowieT

<p>Checks Domain WHOIS Lookup for availability. Simple insert the [pwhois] shortcode on a page or post.<br />
To select the default TLD use the default attribute: [pwhois default=com] – sets .com as default in the TLD dropdown.<br />
TLD List is limited because of the knowledge of the required whois servers. If you wish to have support for a special TLD please contact me and I will implement it asap.<br />
We cannot guarantee that every domain lookup works perfect, in case that whois servers and how to talk to them can change time by time.<br />
However if you inform us about changes and we can get it to work, we give you a free version of the Pro version of this plugin!</p>

Powie's WHOIS Domain Check

Not what I needed. It can only check availability for .com domains, not any TLD as in description. One star for inaccurate description.

LIMITED – only checks .com

Check a Domain WHOIS Lookup for availability. Simple insert the [pwhois] shortcode on a page or post
