Class IPaddress 

java.lang.Object
   |
   +----IPaddress
public class IPaddress
extends Object
This class implements an IP address. An IP address is wrapped around in a class to allow easy changes to its representation later. The current representation is a 32-bit int, which is represented internally in two's-complement.

Constructor Index

o IPaddress()
Constructs an IP address with a random IP value
o IPaddress(int)
Constructs an IP address with the given short array
o IPaddress(int, byte)
Constructs an IP address with the given short array and the subnet mask bits, which can range from 1 to 32
o IPaddress(int, int)
Constructs an IP address with the given short array and the subnet mask bits, which can range from 1 to 32

Method Index

o equals(IPaddress)
returns true if the given ip value is the same, false otherwise
o get()
Returns the value of this IP address
o getIncremented(int)
Returns a new IP address which value is this address incremented by a certain value
o getMask()
Returns the number of bits in the mask
o identical(IPaddress)
compares with another IP to see if they are identical
o increment(int)
Increments this IP address by a certain value
o mask(byte)
Returns an IP address taking the last b bits of this IP address
o mask(int)
Returns an IP address taking the last b bits of this IP address
o next()
Increments this IP address
o printBinary()
Prints the binary value of this IP address
o samePrefix(IPaddress)
Returns true if this IP address and the given IP address has the same prefix.
o set(int)
Sets the value of this IP address
o set(IPaddress)
Sets this IP to the same as another IP
o setMask(byte)
Sets the number of bits in the mask
o toString()
Prints the A.B.C.D representation of this IP address.
o toStringNoMask()
Prints the A.B.C.D representation of this IP, without mask.
