domain name checker?

hi, does anyone know where i can get a domain checker for my site (in asp) ?

would be really helpful!

thanks

What's a domain name checker? You mean a whois lookup?

you will need a third party component to do domain checking in most cases.
however i use the following code to grab the register.com WhoIs data:

index.asp

<form method="POST" action="index.asp?lookup=y">
<p align="center"><input type="text" name="name" size="20"><input type="submit" value="Lookup" name="B1"></p>
</form>
<p align="center">&nbsp;</p>
<%
if request("lookup")="y" then
name = request("name")
response.write "<img src=""http://www.register.com/generate_gif.cgi?msg="&name&""">"
end if
%>
