All of the IP are stored in memory. This takes up about 3.5 GB. I have a text file that is 445K lines that contains all of the specific IP addresses and the IP prefixes (CIDR) that make up that 250 million ips. Uncompressed I do not know. Are you interested in the ranges and ip addresses or a list of all the ip addresses that make up all the ranges as well? Let me know what you need and I could definitely try and accommodate for you.
