C# Class fCraft.IPAddressUtil

Provides utility methods for working with IP addresses and ranges.

Public Methods

Method	Description
AsInt ( [ thisAddr ) : int	Represents an IPv4 address as a signed integer.
AsUInt ( [ thisAddr ) : uint	Represents an IPv4 address as an unsigned integer.
IsIP ( [ ipString ) : bool	Checks to see if the specified string is a valid IPv4 address.
IsLocal ( [ addr ) : bool	Checks whether an IP address may belong to LAN or localhost (192.168.0.0/16, 10.0.0.0/24, or 127.0.0.0/24).
Match ( [ thisAddr, uint otherAddr, uint mask ) : bool
NetMask ( byte range ) : uint	Creates an IPv4 mask for the given CIDR range.
