This is a project that checks if an IP is within a known IP-address range of cloud service providers.
The intention of this library is just to gather data of user behaviour.
If you think security-wise, a firewall rule is probably a better option. Or buy the DNS/WHOIS lookup database records.
Currently supported IP-address ranges to identify:
- LocalIp
- CloudFlare
- Fastly
- AWS
- GitHub
The principle of this library is:
- Collect the latest ip-address ranges file (CIDR routing tables) from the provider
- Check if your given IP matches within that range.
- Supports both IPv4 and IPv6 via System.Net.IPNetwork.
- Supports IPv4.
- Maps IPv6 to IPv4.
Usage:
// Single:
let found, provider = CloudIP.Cloudservices.checkIp "192.168.1.0"
// Multiple:
let checkedIps = CloudIP.Cloudservices.checkIps [| "123.123.123.123"; "173.245.48.15" |]
checkedIps |> Array.iter(fun res -> printfn "%O" res)
