Does Google hesitate on dynamic DNS domains?

Incomplete crawling of local hosted dynamic domains.

[killroy]

I usually have teh next verssion of my websites running on a local server using a dynamic DNS domain with wildcard subdomains.

Google sometiems seems to pick up stray external links and index a few homepages form those domains. I don't mind at all as the pages are usually in an advanced stage and can bear visitors. Furthermore it would let me get an idea of googleability of those new sites.

But Google seems to be reluctant to spider these domains as deeply and thouroughly as normal domains. Is this just a feature of my specific sites or of the fact that it's a dynamic DNS hosted domain?

Anybody else have experieces with google and dynamic DNS domains?

Thanks,

SN
