You can put the search form of IP-DOMAIN-LOOKUP in your homepage.
You will put the following HTML sauce in your page. <FORM ACTION="http://www.mse.co.jp/cgi-bin/ip_dom-1/ipdo_lookup_e.cgi" METHOD=GET> <INPUT TYPE=TEXT NAME="key" SIZE=38> <INPUT TYPE=SUBMIT VALUE=" IP-Domain-Lookup "></FORM>
It must seem that this form is the next. If this form is used, you can add the search performance of "IP-DOMAIN-LOOKUP" to your page.
[Caution]
NAME= : Don't change "key". Performance can't be assured. SIZE=38 : You don't care .The width of the window only changes. VALUE= : We ask to you that you don't change the character of "IP-Domain-Search". ACTION= : Never change "http://www.mse.co.jp/cgi-bin/ip_dom-1/ipdo_lookup_e.cgi". Performance can't be assured. Especially,when our cgi was used in your CGI and changed with ACTION= "your CGI file name ", we think that you have the intention of the plagiarism.

As for the question, to ipdomain@mse.co.jp, please.
