How to search for a range of IP addresses (example: 10.10.10.32 through 10.10.10.96)?

Does anyone know the criteria to search for a range of IP address under the following conditions. I want to narrow the results down to IP addresses that fall within 10.10.10.32 - 10.10.10.96 or say 10.10.10.1 - 10.10.10.128. I've used the regex _ip="10.10.10.(3[0-9])" and got successful results for addresses in 10.10.10.30-39. But how can I do what I'm asking above. Any help is greatly appreciated. Thanks
