  • Constructor Details

    • CidrBlock

      public CidrBlock(InetAddress inetAddress)
      Creates a CIDR block that only contains the provided IP address (/32 if IPv4, /128 if IPv6)

    • CidrBlock

      public CidrBlock(InetAddress inetAddress, int prefixLength)

    • CidrBlock

      public CidrBlock(byte[] address, int prefixLength)

  • Method Details

    • getInetAddress

      public InetAddress getInetAddress()
      Returns:
      The first IP address in this CIDR block

    • prefixLength

      public int prefixLength()
      Returns:
      the number of bits in the network mask

    • isIpv6

      public boolean isIpv6()

    • contains

      public boolean contains(InetAddress address)
      Returns:
      true iff the address is in this CIDR network.

    • resize

      public CidrBlock resize(int newPrefixLength)
      Returns a copy of this resized to the given newPrefixLength

    • clearLeastSignificantBits

      public CidrBlock clearLeastSignificantBits(int bits)

    • clearHostIdentifier

      public CidrBlock clearHostIdentifier()
      Returns:
      a copy of this CIDR block with the host identifier bits cleared

    • getByte

      public int getByte(int byteOffset)
      Return the byte at the given offset. 0 refers to the most significant byte of the address.

    • setByte

      public CidrBlock setByte(int byteOffset, int n)
      Set the byte at the given offset to 'n'. 0 refers to the most significant byte of the address.

    • addByte

      public CidrBlock addByte(int byteOffset, int n)
      Add 'n' to the byte at the given offset, truncating overflow bits. 0 refers to the most significant byte of the address.
