⁠IP Checker

• Check IPs against a large set of IP ranges.
• Pass in a file or URL.
• Checks against known datacenter IP ranges⁠ by default, using data from this project⁠.
• Uses an Interval Tree for fast matching. Able to check 500k IPs against >33k IP ranges in a couple of seconds (on my MacBook Pro).
