Welcome to WebmasterWorld Guest from 126.96.36.199
188.8.131.52 resolves to the IP block used by capitalnet.com.cn, a Chinese ISP tagetted at business. It could be a dialup account, or a small company, or... As to why they are spidering you, depends on your site.
Hope this hbelps
Thanks for the IP info Woz.
If that is a dial up IP, can you run a spider on a dial up?
