Googlebots And Sub-domains Are Subdomains Indexed by the Bots???

[jlhaslip 4]

I don't know if this is the correct forum for asking, but here goes. If someone has an opinion about where this question is better placed, please move it or let me know...My Xisto subdomain (jlhaslip.trap17.com) has been visited by 4 or 5 Bots this month. I have several different sites hosted as subdomains. (ie: sub1.jlhaslip.trap17.com and sub2.jlhaslip.trap17.com). Each of these subdomains have different content and are unrelated.When the Bots visit, do they investigate all the subdomain index pages for their content and index them seperately? If so, how do I check for the page ranking of each subdomain?Thanks for reading this and replying.
