    • add

      public SocketUtilsIPV6.IPv6Address add(int value)
      Addition. Will never overflow, but wraps around when the highest ip address has been reached.
      Parameters:
      value - value to add
      Returns:
      new IPv6 address

    • subtract

      public SocketUtilsIPV6.IPv6Address subtract(int value)
      Subtraction. Will never underflow, but wraps around when the lowest ip address has been reached.
      Parameters:
      value - value to subtract
      Returns:
      new IPv6 address

    • isLessThanUnsigned

      private boolean isLessThanUnsigned(long a, long b)

    • maskWithNetworkMask

      public SocketUtilsIPV6.IPv6Address maskWithNetworkMask(SocketUtilsIPV6.IPv6NetworkMask networkMask)
      Mask the address with the given network mask.
      Parameters:
      networkMask - network mask
      Returns:
      an address of which the last 128 - networkMask.asPrefixLength() bits are zero

    • maximumAddressWithNetworkMask

      public SocketUtilsIPV6.IPv6Address maximumAddressWithNetworkMask(SocketUtilsIPV6.IPv6NetworkMask networkMask)
      Calculate the maximum address with the given network mask.
      Parameters:
      networkMask - network mask
      Returns:
      an address of which the last 128 - networkMask.asPrefixLength() bits are one

    • isIPv4Mapped

      public boolean isIPv4Mapped()
      Returns true if the address is an IPv4-mapped IPv6 address. In these addresses, the first 80 bits are zero, the next 16 bits are one, and the remaining 32 bits are the IPv4 address.
      Returns:
      true if the address is an IPv4-mapped IPv6 addresses.

    • toString

      public String toString()
      Returns a string representation of the IPv6 address. It will use shorthand notation and special notation for IPv4-mapped IPv6 addresses whenever possible.
      Overrides:
      toString in class Object
      Returns:
      String representation of the IPv6 address
