                int newmask)

Method Detail

getEndAddress

public java.net.InetAddress getEndAddress()

Specified by:

getEndAddress in class CIDR

Returns:

the end address of this block.

compareTo

public int compareTo(CIDR arg)

contains

public boolean contains(java.net.InetAddress inetAddress)

Description copied from class: CIDR

Compares the given InetAddress against the CIDR and returns true if the ip is in the subnet-ip-range and false if not.

Specified by:

contains in class CIDR

Returns:

returns true if the given IP address is inside the currently set network.

ipv6CidrMaskToBaseAddress

private static java.math.BigInteger ipv6CidrMaskToBaseAddress(int cidrMask)

Given an IPv6 baseAddress length, return the block length. I.e., a baseAddress length of 96 will return 2**32.

ipv6CidrMaskToMask

private static java.math.BigInteger ipv6CidrMaskToMask(int cidrMask)

ipv6AddressToBigInteger

private static java.math.BigInteger ipv6AddressToBigInteger(java.net.InetAddress addr)

Given an IPv6 address, convert it into a BigInteger.

Returns:

the integer representation of the InetAddress

Throws:

java.lang.IllegalArgumentException - if the address is not an IPv6 address.

bigIntToIPv6Address

private static java.net.InetAddress bigIntToIPv6Address(java.math.BigInteger addr)
                                                 throws java.net.UnknownHostException

Convert a big integer into an IPv6 address.

Returns:

the inetAddress from the integer

Throws:

java.net.UnknownHostException - if the big integer is too large, and thus an invalid IPv6 address.
