IpSet

A simple tool to enumerate IpAddress and check if an IP address is contained by the defined range or set.

Support both IPv4 and IPv6.

Support CIDR notation.

Install from NuGet

In the Package Manager Console:

PM> Install-Package IpSet

Use IpRange

IpRange represents a consecutive IP addresses.

Check an IP address.

    var range = IpRange.ParseOrDefault("192.168.0.0/16");
    var result = range.Contains("192.168.2.99"); // true

Support multiple parsing formats.

    [Theory]
    [InlineData("192.168.0.10 - 192.168.10.20", "192.168.20", true)]
    [InlineData("192.168.0.*", "192.168.0.255", true)]
    [InlineData("192.168.0.*", "192.168.1.0", false)]
    [InlineData("192.168.0.0/255.255.255.0", "192.168.1.100", false)]
    [InlineData("192.168.0.0/16", "192.168.2.99", true)]
    [InlineData("fe80::/10", "192.168.0.1", false)]

Use IpSet

IpSet represents a group of IpRange instances. Ranges should be separated by comma when parsing.

IpSet is the recommended class over IpRange since it can hold one or multiple ranges. More features will be added on it later.

Check an IP address.

    var set = IpSet.ParseOrDefault("192.168.0.*,10.10.1.0/24,fe80::/10");
    var result = set.Contains("192.168.2.99"); // false
    result = set.Contains("10.10.1.200"); // true
    result = set.Contains("fe80::"); // true

Support multiple parsing formats.

Support any string conjunctions of IpRange formats by comma(","). Such as:

var set = IpSet.ParseOrDefault("192.168.0.10 - 192.168.10.20, 192.168.1.*, fe80::/10, 10.10.1.200");
