I stumbled upon this note on vlsm. The question goes like: An isp is granted block of addresses starteing with 190.100.0.0/16 (65,536 adds). The isp needs to distribute the addresses to 3 groups of customers: Group 1. 64 customers; each needs 256 address Group 2. 128 ... for several semester for this. Please help me. Isn't there any simpler answer? I don't want to waste my time too much on this.
