AbstractIPAddressRange

The AbstractIPAddressRange is an abstract implementation of IIPAddressRange. It is extended by both IPAddressRange, and Subnet.

Functionality Implementation

IFormatable

Extensions of AbstractIPAddressRange, depending on overrides and implementation, provide a general format (G, g, or empty string) that will express a range of IP addresses in a head - tail format for example 192.168.1.1 - 192.168.1.10.

[Fact]
public void IFormattable_Example()
{
    // Arrange
    var head = IPAddress.Parse("192.168.0.0");
    var tail = IPAddress.Parse("192.168.128.0");
    var ipAddressRange = new IPAddressRange(head, tail);

    const string expected = "192.168.0.0 - 192.168.128.0";

    // Act
    var formattableString = string.Format("{0:g}", ipAddressRange);

    // Assert
    Assert.Equal(expected, formattableString);
}
