Subnets required to match a range

Does anyone know of a quick algorithm (ideally excel) or online resource to calculate the minimum set of subnets required to positive match a range of IP addresses. For example, 10.10.10.1 to 10.10.10.10 would consist of:

• 10.10.10.1/32 (10.10.10.1)
• 10.10.10.2/31 (10.10.10.2 - 3)
• 10.10.10.4/30 (10.10.10.4 - 7)
• 10.10.10.8/31 (10.10.10.8 - 9)
• 10.10.10.10/32 (10.10.10.10)
