Hi, is there a standard or a practice on how much IP addresses an ISP should
provide to his/her client given that this client has bought only 2Mb of
bandwidth and this client is an ISP?

Umm.. don't bother.  Let's think this through.  2Mbits/sec of bandwidth
will only sustain about 40 56KB modems doing a simultaneous download.

Even adding in think time and the like, a /24 should be plenty wide enough.

Not really...I regularly see 180+ lines filled and BW utilization averages
about 800-900kbps.  This is with a couple hundred websites, outsourced
news a dedicated DS0 customer that stays pegged almost all the time and
several colocated servers.

I'll bet this has been hashed here a few times...
