IP addresses indexed?

[DenverKelly]

I've met with a potential client who has a site with 1,000's of very specific part #'s which don't show in the SERP's on Google. They definitely have the issue of dynamic URL's - but the URL for the part # searches is an IP address rather than their domain name - example:

188.888.888.888/partssearch.php?pnum='1233445'

I've not seen the IP address used like this for an external website - is this acceptable for SEO purposes?

Thanks,

Mark

Can't they change it to a human-friendly form? I don't think it's beneficial for SEO. Google strives for being human-friendly. Your client should move into the same direction.
